Umphrey's McGee

Umphrey's McGee is an American progressive rock/jam band originally from South Bend, Indiana, now based in Chicago, Illinois.

Though the band's approach to their live performances has much in common with Phish and the Grateful Dead (ever-changing setlists, constant improvisation, two sets per night, open-taping policy), they are much more influenced musically by progressive rock bands such as King Crimson, Yes, Pink Floyd, Dream Theater, Frank Zappa, and Genesis, as well as heavy metal bands such as Iron Maiden. The band also identifies The Police, The Beatles, and Led Zeppelin as primary influences.
