Umphrey's McGee is a progressive rock/jam band from South Bend, Indiana whose music is often referred to as "progressive improvisation."

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. Artists covered in concert by Umphrey's range from Lionel Richie to Metallica to Toto to Snoop Dogg to Paul Simon to Radiohead to The Rolling Stones.
