The live attempts at recreating the seminal jam chemistry of Super Session were hit-and-miss affairs, and this one, previously unreleased, has its fair share of off-key and off-target tunes. The rhythm section is erratic, the repertoire–ranging from Simon & Garfunkel's "59th Street Bridge Song (Feelin' Groovy)" to an Elvis-flavored "That's All Right Mama"–is a bit odd, and co-leader Al Kooper is competent but rarely inspired. Guitarist Michael Bloomfield, however, is uniformly brilliant and his graceful blues virtuosity is by itself well worth the price of admission. Bloomfield and the group are joined on B.B. King's "It's My Own Fault" by a then-unknown Johnny Winter and things get really interesting.

As the Beatles' Sgt. Pepper's Lonely Hearts Club Band (1967) had done a year earlier, Super Session (1968) initially ushered in several new phases in rock & roll's concurrent transformation. In the space of months, the soundscape of rock shifted radically from short, danceable pop songs to comparatively longer works with more attention to technical and musical subtleties. Enter the unlikely all-star triumvirate of Al Kooper (piano/organ/ondioline/vocals/guitars), Mike Bloomfield (guitar), and Stephen Stills (guitar) – all of whom were concurrently "on hiatus" from their most recent engagements. Kooper had just split after masterminding the groundbreaking Child Is Father to the Man (1968) version of Blood, Sweat & Tears. Bloomfield was fresh from a stint with the likewise brass-driven Electric Flag, while Stills was late of Buffalo Springfield and still a few weeks away from a full-time commitment to David Crosby and Graham Nash. Although the trio never actually performed together, the long-player was notable for idiosyncratically featuring one side led by the team of Kooper/Bloomfield and the other by Kooper/Stills.

Child Is Father to the Man is keyboard player/singer/arranger Al Kooper's finest work, an album on which he moves the folk-blues-rock amalgamation of the Blues Project into even wider pastures, taking in classical and jazz elements (including strings and horns), all without losing the pop essence that makes the hybrid work. This is one of the great albums of the eclectic post-Sgt. Pepper era of the late '60s, a time when you could borrow styles from Greenwich Village contemporary folk to San Francisco acid rock and mix them into what seemed to have the potential to become a new American musical form. It's Kooper's bluesy songs, such as "I Love You More Than You'll Ever Know" and "I Can't Quit Her," and his singing that are the primary focus, but the album is an aural delight; listen to the way the bass guitar interacts with the horns on "My Days Are Numbered" or the charming arrangement and Steve Katz's vocal on Tim Buckley's "Morning Glory." Then Kooper sings Harry Nilsson's "Without Her" over a delicate, jazzy backing with flügelhorn/alto saxophone interplay by Randy Brecker and Fred Lipsius.

The best of all of Al Kooper's studio albums, Rekooperation is a mostly instrumental album, on which the artist (playing organ and piano, and occasional guitar) and a band including Jimmy Vivino, Harvey Brooks, and Fred Walcott, among others, roar and pound their way through a baker's dozen of R&B, rock & roll, and soul classics. Everything from chestnuts like "Soul Twist," "Honky Tonk," "Johnny B. Goode," "Clean Up Woman," and " "Don't Be Cruel" to originals such as "Downtime" and "Alvino Johnson's Shuffle," without a notable gap in quality between them, are included – and the one vocal number, "I Wanna Little Girl," contains one of the finest singing performances that Kooper has ever turned in on record (but is also played so well, that it would work as an instrumental too). In many ways, this recording is a distant cousin to Blood, Sweat & Tears' Child Is Father to the Man, and was his first attempt at leading a band since that 1968 venture, which was sort of fitting since it led to Soul of a Man, Kooper's live-in-concert career retrospective album, the next time out.
