In 1971, the Jazz Crusaders reinvented themselves for the first time. First they dropped the word "jazz" from their moniker, and secondly they wholeheartedly embraced electric bass and guitars in their mix. Their new "debut" is a wonder of jazz-funk as a natural evolution out of hard bop and soul-jazz. While the wonderful horn interplay between saxophonist Wilton Felder and trombonist Wayne Henderson is still everywhere evident, the badass, beat-driven rhythm section has Joe Sample playing funky Rhodes piano against Chuck Rainey's basslines and an orgy of guitars – led by Larry Carlton's brilliant lead work. These are all anchored by Stix Hooper's never out-of-the-pocket, popping kit work. Certainly other acts had used the same instrumentation, but the sheer sophistication in the Crusaders compositions and charts combined with their dedication to grooved-out accessibility – and Stewart Levine's magnificent production – made them a singular entity even in the up-and-coming jazz-rock fusion scene.

When trombonist/producer Wayne Henderson, pianist/keyboardist Joe Sample, sax-man Wilton Felder, and drummer Stix Hooper changed their name from the Jazz Crusaders to the Crusaders back in 1971, it signaled a more R&B-minded direction for the group – they were always funky, but in the '70s, they became even funkier. And so, the names the Crusaders and the Jazz Crusaders came to stand for two different things – if the Jazz Crusaders were synonymous with a funky yet acoustic-oriented approach to hard bop (à la Art Blakey's Jazz Messengers), the Crusaders were about electric-oriented jazz-funk and fusion. In 1995, Henderson (who left the Crusaders in 1975) resurrected the name the Jazz Crusaders and produced Happy Again for the small, Los Angeles-based Sin-drome Records.
