Though I don't know these early Verves, I do own one Nimmons release, SANDS OF TIME (2000), on Sackville. A quartet date with pianist Gary Williamson, bassist Steve Wallace, and drummer Barry Elmes. Fine playing -- Nimmons has a "chesty" tone -- as well as pleasant and often distinctive compositions by the leader. In terms of showing off his virtuosity, he strikes me a bit more Tony Scott-like than Buddy DeFranco-esque, if that makes any sense.
