Although his tenure with Willie Dixon at Chess Studios is what made him a star, Howlin' Wolf's short-lived association with Ike Turner, Sam Phillips, and Sun Studios in the early '50s produced some of the most powerful and raucous music ever recorded. (Muddy Waters' first electric recordings are downright tame in comparison.) The Wolf Is at Your Door is a sizeable chunk of Howlin' Wolf's Sun sessions - a diverse slate of music recorded over the span of 11 months. Seven of these songs (including the legendary "Moanin' at Midnight" b/w "How Many More Years") were leased to Chess, while the rest were left unissued until the late '70s. This is about as unrestrained as Wolf ever got in a studio setting, thanks in part to the crude backing he got from guitarist Willie Johnson and drummer Willie Steel…

Those who became aware of Robert Randolph's considerable musical gifts on either the awesome Live at the Wetlands or on the underrated Unclassified are in for a surprise. Colorblind expands the Robert Randolph & the Family Band's palette – on tape anyway, they've been doing stuff like this on the stage for years – stretching out from the blues ledge into gospelized, gritty funk and soul, and expanding those genres in the process. Using a group of producers from cut to cut, the Family Band takes no prisoners in this wildly crazy and utterly joyous mix of musical forms and flavors. Sure, it's a bit slicker than Live at the Wetlands, but not in any detrimental way. This is what these cats have been laying down for awhile now. It's been their vision and they've finally brought it into the studio. The opening joint is a stomping wail called "Ain't Nothing Wrong with That" that features the Family Band chanting a refrain, handclaps, and killer female backing vocals as well as Jason Crosby's B-3, as Randolph's pedal steel hovers above before coming in for the killing groove.

The second full-length from sacred steel genius Robert Randolph & the Family Band delivers, from the studio, the same promise, grit, grease, and sweat that Live at the Wetlands did. Randolph pulls out the stops in the studio, using his own band, without any of the hotshot guest stars who he's appeared with in the last two years. Unclassified features a road-tested, studio-savvy band using all of its collected gifts with producer Jim Scott to make a record that is as much about soul, funk, hard rock, folk, and jam band intensity as it is about the gospel music that first inspired the unit.

Whoa. There are many Etta James collections out there. The standard-bearers thus far have been the Chess Box and the Essential Etta James. This set attempts to do something else and goes deep into her catalog to dig out the gems from her years with Modern, Argo, Cadet, Chess, Warner Brothers, Island, and Private Music/BMG, and presents the full spectrum of her five-decade career. As such, there are many different kinds of songs here revealing the complexity of the vocalist herself, and as such, thus becomes a real portrait of the artist. Juxtapose, for instance, early sides like "The Wallflower Dance (Dance With Me Henry)," with its wild R&B bravado and the deep soul-blues of "All I Could Do Is Cry," the balladry of "The Man I Love," the bone-crushing blues of "The Sky Is Crying," and the torch song ballad technique on "My Dearest Darling," and the despairing soul inherent in songs such as "All the Way Down," and the listener begins to get an idea of just how vast and deep James talent really is. These 23 cuts give a fine and full picture of all that diversity without sacrificing a note of quality.

With a passel of familiar faces in the cast (ex-James Brown bassist Tim Drummond, pianist Dumpy Rice, harpist Rusty York), the reclusive Mack rocks up some memorable dusties his way – the Falcons' "I Found a Love," and Bobby Bland's "Share Your Love with Me," Little Walter's "My Babe," and Jimmy Reed's chestnut "Baby What You Want Me to Do," along with his own "Gotta Be an Answer".

Bobby Rush got dirty on 2013's Down in Louisiana but with 2014's Decisions, he returns to his slick blues-funk ways, but this doesn't mean it's a rote affair by any means. He has teamed up with the band Blinddog Smokin' and, for the first time in his career, recorded with fellow Louisiana legend Dr. John. Mac Rebennack shows up on the opening "Another Murder in New Orleans," a deeply soulful and searching portrait of the violence that often plagues the Big Easy but, really, that's the only instance when good times aren't on Rush's mind. He leers about being a "Funky Old Man" and winks about what happens on "Bobby Rush's Bus," two songs that set the pace and attitude for much of the rest of Decisions.

As the title suggests, this is the definitive edition of Etta James' Tell Mama long-player. For this single-disc release the original album is augmented with five previously unissued tracks – documented during James' four Muscle Shoals sessions circa '67-'68. The question of why a rural Alabama town became a conduit for some of the most memorable and instantly identifiable grooves may still be up for debate. The evidence exists in droves and Tell Mama could certainly be considered exhibit A. These sessions feature the same impact that would redirect several first ladies of soul. Notable among them are Dusty Springfield's Dusty in Memphis, Aretha Franklin's I Never Loved a Man (The Way I Love You) and to somewhat lesser acclaim, Jackie DeShannon's Jackie. Tell Mama showcases some of the unique and admittedly darker qualities of what might best be described as R&B noir. "I'd Rather Go Blind," "Steal Away," "I'm Gonna Take What He's Got" all exemplify the essence of the blues – making the best of a bad situation.

B.B. King has cut a lot of albums since the success of Live at the Regal. And, like the live shows they document, none of them are any less than solid and professional, hallmarks of King's work aesthetic. But every so often B.B. truly catches fire; his playing and singing comes up an extra notch or two, and the result is a live album with some real sparks to it. Live in Cook County Jail is one of those great concerts that the record company was smart enough to be there to capture, documenting B.B. firing on all cylinders in front of an audience that's just damn happy for him to be there. Possibly the best live version of "The Thrill Is Gone" of all its many incarnations, and rock solid renditions of classics like "Everyday I Have the Blues," "How Blue Can You Get?," "Sweet Sixteen" and a great medley of "3 O'Clock Blues" and "Darlin' You Know I Love You"…

18 Essential Songs is a one-disc distillation of the triple-disc Janis box set. Running 70 minutes, it is a more extensive best-of than the ten-track 1973 Janis Joplin's Greatest Hits album.

Come a Little Closer is a surprisingly effective mating of a distinctive singer with seemingly incongruous material and production. Helmed by Gabriel Mekler, who'd produced Steppenwolf and Three Dog Night, the record features Etta James supported by a slew of hotshot L.A. session men (including Little Feat's Lowell George). The song selection ranges from "St. Louis Blues" to Randy Newman's perverse "Let's Burn Down the Cornfield" to the dramatic, melismatic "Feeling Uneasy," in which the junk-hungry James improvised wordlessly over an otherwise blues progression. Here's more evidence that Etta is one of the most versatile vocalists of her era.

Leonard Chess dispatched Etta James to Muscle Shoals in 1967, and the move paid off with one of her best and most soul-searing Cadet albums. Produced by Rick Hall, the resultant album boasted a relentlessly driving title cut, the moving soul ballad "I'd Rather Go Blind," and sizzling covers of Otis Redding's "Security" and Jimmy Hughes' "Don't Lose Your Good Thing," and a pair of fine Don Covay copyrights. The skin-tight session aces at Fame Studios really did themselves proud behind Miss Peaches.
