Four of the tracks on this 1960 album are also on Charles Mingus And The Newport Rebels. The fifth one, Wrap Your Troubles In Dreams, is probably from that same set of sessions because it features Roy Eldridge on trumpet and Papa Jo Jones on drums.
The tracks are certainly off the beaten path in one respect, but some of Mingus' regulars, such as Eric Dolphy and Booker Ervin are also included (especially Mingus' musical soulmate Dannie Richmond on drums). They share Bugs, with Dolphy and Richmond accompanying Mingus on Body and Soul and R&R. Roy Eldridge is also on the last two.
If you are a Mingus fan you will enjoy the entire album. If you are new to Mingus, but love straight ahead, hard swinging jazz, you should also love this album and particularly the last four tracks. And, as importantly, if you are a jazz history buff, the back story to this and the Newport Rebels album cited above adds a layer. By 1960 black musicians had grown disenchanted with that they considered to be poor treatment by the Newport Jazz Festival organization. Mingus and Roach were always strong personalities and leaders, so they put on a parallel concert in 1960. It wasn't recorded, but this album and the Reincarnation Of A Love Bird one were recorded in the studio shortly afterwards, produced by Nat Hentoff.
This album is a part of a value-priced set called 5 Classic Albums, which I highly recommend.
