Clockwork, 2004 Harmony Sweeps National Finals 1st runners up, is comprised of veteran San Francisco Bay Area harmony singers whose members have sung in several acclaimed a cappella groups. Two are founding members of Phil Mattson's PM Singers and Eric Freeman is the only singer to reach the National Finals in three different groups. Sophisticated jazz arrangements are a stand out on this EP including some complex harmonized bebop, the fabulous Brazilian classic " Corcovado" and a swinging Gershwin medley. This is smart, clever stuff!
