The music of Umphrey’s McGee unfolds like an unpredictable conversation between longtime friends. Its six participants—Brendan Bayliss [guitar, vocals], Jake Cinninger [guitar, vocals], Joel Cummins [keyboards, piano, vocals], Andy Farag [percussion], Kris Myers [drums, vocals], and Ryan Stasik [bass]—know just how to communicate with each other on stage and in the studio. A call of progressive guitar wizardry might elicit a response of soft acoustic balladry, or a funk groove could be answered by explosive percussion. At any moment, heavy guitars can give way to heavier blues as the boys uncover the elusive nexus between jaw-dropping instrumental virtuosity and airtight songcraft.
