Umphrey’s McGee: 7 p.m. Monday, Boulder Theater, 2032 14th St., Boulder. In the 25 years since the eclectic improv-rock band Umphrey’s McGee formed, its sound has been an amalgamation of genres, moods and tempos, effortlessly flowing from one feeling to the next throughout an album or concert — or sometimes within a singular song. But with time and repetition comes wisdom and maturity, both personally and musically, and in the case of the band’s new album “Asking For A Friend,” Umphrey’s McGee entered the recording studio with something to say and a wise, measured way to say it.The end result is a cohesive 14-song album that feels like a fresh statement from a group of world-class musicians and friends reapproaching their craft with a new lens. $49.50-$129.50, z2ent.com.
