Caveman was a British hip hop group originally from High Wycombe, England, consisting of MCM, the Principal, and Diamond J.
This established their jazz-based style of hip hop, influenced by U.S. artists such as Gang Starr.
The song "I'm Ready", however, was based on Jimi Hendrix's, "Crosstown Traffic" and showed early on a liking for the harder style that they adopted for later releases.
"I'm Ready" was a popular song, and still regularly turns up on hip hop compilation albums today.
[1] MCM had a short-lived solo career, releasing some twelve inches and guesting on other artists' tracks - such as Dodge City Productions' "Understand This" from their Steppin' Up and Out (4th & Broadway, 1993) album.
