This is 1970s Uk reggae. The Undivided featured Rico on trombone. Rico loved this group (for details see the Jama Rico Wiki here). I've got a Cd copy by one of my fellow lovers for Rico's music while I was compiling Rico's discography. Nobody seems to remember this LP, you even can't find at The Reggae Archive. With this rip comes the second LP by the band, The Original Undivided.
