An atmosphere of early morning in the Shoyama mountains of Japan. The sun rises above a mountain crest. A monk rings the bell, signalling the time for prayer. It is in such surroundings that Kosei Yamamoto takes his saxophone and warms up on filigree improvisations, to a background of natural sounds. His friends Hiroki and Takashi used a digital MTR and mixer to record this sound, which tunes in to the earth’s gravity.

One of the finest acoustic guitar innovators borne of the late '70s UK folk scene, was in Philadelphia early 2010, paying tribute to his good friend, the late Jack Rose, a mighty six-string alchemist in his own right, and a youngster wholly inspired by Chapman's critical recordings. While sharing in the good light of friendship backstage, we asked Michael if he'd ever recorded an LP of purely improvised guitar music. It seemed feasible, as the current state of acoustic guitar exploration was in equal measures inspired by both composition and improvisation. Chapman, along with Bert Jansch, John Renbourn, John Fahey et al, was a significant and historical informant for this young set.

Captain Beyond's second album must have confused the diehards. Where their self-titled debut had upheld the basic progressive heavy rock blueprint of lengthy instrumental explorations, constant tempo changes, and opaque, yet cinematic lyrics, Sufficiently Breathless downplays them for a subtler, song-oriented production. The predominant mood is snappy and businesslike; no track runs over five and a half minutes. This newfound conciseness certainly benefited such heavy-rocking efforts as "Distant Sun," even as the band stuck to their diverse guns on the moody, acoustic title track and the sleek Latin funk rock of "Bright Blue Eyes" and "Everything's a Circle." The results were intelligent and self-assured, yet the band's never-ending bad luck again intervened when vocalist Rod Evans quit in late 1973, leaving the album adrift. The band would proffer a markedly different style on their return four years later, but anyone dismissing progressive heavy rock as an oxymoron should definitely check out this album first.

Jefferson Airplane's first live album demonstrated the group's development as concert performers, taking a number of songs that had been performed in concise, pop-oriented versions on their early albums - "3/5's of a Mile in 10 Seconds," "Somebody to Love," "It's No Secret," "Plastic Fantastic Lover" - and rendering them in arrangements that were longer, harder rocking, and more densely textured, especially in terms of the guitar and basslines constructed by Jorma Kaukonen and Jack Casady. The group's three-part vocal harmonizing and dueling was on display during such songs as a nearly seven-minute version of Fred Neil's folk-blues standard "The Other Side of This Life," here transformed into a swirling rocker…

Closer to Home, the trio's third album, was the record that really broke them through to the commercially successful level of metal masters such as Led Zeppelin and Black Sabbath. Rather than rushing headlong into their typical hard, heavy, and overamplified approach, Grand Funk Railroad began expanding their production values. Most evident is the inclusion of strings, the acoustic opening on the disc's leadoff cut, "Sins a Good Man's Brother," as well as the comparatively mellow "Mean Mistreater." But the boys had far from gone soft. The majority of Closer to Home is filled with the same straight-ahead rock & roll that had composed their previous efforts.

Although John Lewis is listed as the leader (this album's alternate title is "John Lewis Presents Contemporary Music"), the pianist does not actually appear on this record and only contributed one piece ("Django"). On what is very much a Gunther Schuller project, Schuller composed "Abstraction" and was responsible for the adventurous three-part "Variants on a Theme of John Lewis (Django)" and the four-part "Variants on a Theme of Thelonious Monk (Criss-Cross)"; Jim Hall contributed "Piece for Guitar & Strings." One of the most successful third stream efforts, this LP combines avant-garde jazz with aspects of classical music. Among the more notable stars, altoist Ornette Coleman is on "Abstraction" and "Criss Cross" (both of which have been reissued in his Rhino CD box) and multi-instrumentalist Eric Dolphy is on both of the "Variants"…
