Remastered by persons unknown this Atlantic re-release, unplayed in my vinyl collection for 20 years or more, gives immense pleasure in it's new incarnation. Recorded just before the recently reissued "Red Clay" Hubbard is in devastating form. He dominates the whole album, and is regally supported by a host of luminary sidesmen of whom Gerry Jemmott(Bass) and Bernard Purdie/Grady Tate (drums) give their all as a rhythm section.The real 'find' from the remaster is just how important a part the unsung Gary Illingworth (organ) played in the sessions. Add to that Eric Gale who plays fluid,funky and singing guitar on seven of the tracks, and Carlos Garnett on Tenor who mostly sits and plays behind Hubbard, before breaking loose on his own composition "Hang 'em high" Favourite tracks are the funky "Clap your hands", the wonderfully slinky "Midnite Soul" and the title track "A soul experiment". There isn't a bad track on this album, and even the seemingly obligatory pop track "Wichita Linesman" stands up. This may be a well hidden reissue, but it's one that deserves the attention of anybody who is getting into Hubbard through that "Red Clay" reissue.Try and listen to it!Finally, having heard him wailing on this album isn't it about time that someone re-released Eric Gale's Elektra Musician album "Island Breeze" from 1983?
