Released in 1966, this album is considered to have shattered the defination what the traditional blues should of sounded like. A era defining album that had a big influence on many that would follow like the Allman Brothers, Fleetwood Mac, the Grateful Dead, amongst others. The band cooks up an experimental fusion of blues and jazz. Two great guitarists, Mike Bloomfield and Elvin Bishop dual it out. Also noted for its stereo quality at that time.
