Super talented group of guys that included Al Kooper on Keys and vocals, Tommy Flanders on vocals, Danny Kalb playing guitar, Steve Katz on guitar and vocals, Andy Kulberg playing bass and flute, and Roy Blumenfield on drums!
Blues Breakers - John Mayall with Eric Clapton (1966)
When it comes to British blues, it doesn't get much better than this, with John Mayall on vocals, keys, and Harp, Slow Hand Clapton on guitar, Fleetwood Mac's John McVie on bass, and Hughie Flint on the traps! It might be the blues, but it's rock solid!
The Paul Butterfield Blues Band - "East - West" (1966)
With songs written by everybody from Mike Nesmith to Muddy Waters, two amazing guitarists Mike Bloomfield and Elvin Bishop, a 13 minute epic psych title song, and a great cover, this album has it all! Paul Butterfield on harp and vocals, Mark Naftalin on keys, Jerome Arnold on Bass, and Billy Davenport on Drums!!
"Spider" John Koerner, Tony "Little Sun" Glover" and Dave "Snaker" Ray - "Lots More Blues, Rags and Hollers" (1964)
Folk Blues at it's finest hour!
Climax Chicago Blues Band - "Tightly Knit" (1971)
Before they became the Climax Blues Band, they were known as the Climax Chicago Blues Band! This is not my favourite cover by any means, but the music inside is good enough to make up for it!
