The full moon actually occurs the day before the gig, but it's close enough for Warp 10, Hyde Park and Floodplane to name their show after it. The Full Moon Jam Fest brings together three Des Moines bands who are all friends and have talked about putting on a show together for what seems like forever.

The show will open with Warp 10, a quartet who played together in the late '70s and early '80s. After being apart for 15 years, the group has regrouped and returned to jamming. Greg Cloe, guitar and vocals; Greg Leeper, bass and vocals; Mark Owen, drums; and Bill Cosgrove, keyboards, guitar and vocals base their sound off bootlegs by bands such as the Grateful Dead and Sons of Champlin. Playing off these song structures, they then improvise into new territory (or "warp out" as they like to call it.)

Following Warp 10 will be alternating sets by Hyde Park and Floodplane. Hyde Park is James Biehn, guitar and vocals; Jason Kent, bass, vocals; Spencer McGinnis, percussion and vocals; and Nathan Peoples, woodwind, keyboard and vocals. All veterans of the Des Moines music scene, the group plays a diverse set of music that capitalizes on their disparate backgrounds. Hyde Park's groove is jazz influenced but stretches into new, uncharted areas.

Floodplane is a jam rock band heavy on vocal harmonies. The four-piece improvisational group consists of Billy Kearney, guitar and vocals; Todd Cummings, drums; Justin Karl, bass and vocals; and Gwen Page, keys and vocals. Floodplane plays mostly original music, but adds a cover tune every now and then.

The show will end with a super jam at midnight, with members of each group joining together on stage. The all-ages show will offer free beer while it lasts for those of legal age and advanced tickets can be purchased at Peeple's Music, Raccoon River Brewing Co. and Hotel Fort Des Moines.
