The big gigs: Sammy Hagar & the Circle, GRiZ

The weather may not scream outdoor concerts, but rock vet Sammy Hagar is always ready to scream, indoors or out. The Van Halen and Montrose alum brings his current group — featuring original Van Halen bassist Michael Anthony, Led Zeppelin drum scion Jason Bonham and hotshot guitarist Vic Johnson — to kick off the season at Mystic Lake amphitheater. The group is touring behind their week-old second album, "Space Between," a hard-rockin' collection obsessed with money, greed and corruption, best exemplified on the rollicking single "Trust Fund Baby." Opening is Vince Neil of Mötley Crüe infamy. (7:30 p.m. Fri., Mystic Lake Casino, Prior Lake, $49-$199, ticketmaster.com)

JON BREAM

With such heavy hitters/one-hitters as Snoop Dogg, Wiz Khalifa and Matisyahu guesting on his new album, "Ride the Waves," Michigan electro-funk producer Grant Kwiecinski, 28, is moving fast toward the pop and R&B mainstream after working his way up the lineups at EDM and psychedelic/jam-band festivals for a half-decade. The album and his live show incorporate his sax-playing skills, love for classic soul music and LGBT pride, which extends to his support for the It Gets Better Project on tour. Yung Bae and Dwilly open. (9 p.m. Fri., Armory, 500 S. 6th St., Mpls., $35-$58, ticketmaster.com.)
