Umphrey’s McGee has built a loyal following since forming in 1997, with constant touring and high-profile spots at Bonnaroo, Forecastle and elsewhere. The band returns in the Iroquois Amphitheater Summer Concert Series, bringing its own unique take on improvised rock. They support the sharing of fan-recorded shows, a la the Grateful Dead and Phish, and are frequently lumped together with other artists in the jam band scene. Musically, though, they draw more from prog rock, with heavier rhythms and arrangements. Their studio albums showcase their writing skills, but it’s the concerts that demonstrate the band’s ability to stretch out. 2007’s Live At the Murat is their most recent official live release, boasting intense interplay and great engineering. More recent live shows find them frequently exploring songs from 10-20 minutes, with segues from one tune into another. Come early for opening act Black Joe Lewis & the Honeybears and hope the weather is cooperative. —Martin Z. Kasdan Jr.
