Stamford-raised John Popper has done a great job keeping his band Blues Traveler relevant and avoiding the one-hit-wonder curse (though they had several hits). The band has been together for a quarter of a century, and many still don't know that they're an ever-evolving multi-genre jam band, not a '90s nostalgia act. But now you do. See them this Friday at the Klein.
Klein Memorial Auditorium, 910 Fairfield Ave., Bridgeport, Fri., Aug. 24, 8 p.m. $37-$62. (203) 259-1036, fairfieldtheatre.org.
