A lot of devil-horns will be raised in the air outside Treasure Island Casino this year, as the Welch/Red Wing-area gambling junction has announced a Judas Priest and Deep Purple co-headlining gig along with a Nickelback date at its outdoor "amphitheater."

JUDAS PRIEST & DEEP PURPLE (SEPT. 20): Each with new albums to promote, the two veteran British hard-rock bands are pairing up for a 25-city tour starting Aug. 21. Ticket info for the Thursday night stop in Minnesota has not yet been released, but prices will probably be similar to the $68-$88 range for the tour stop a night later at Harrah's in Council Bluffs, Iowa.

Not seen locally for nine years, Priest earned good marks for their show three weeks ago at the Armory in Minneapolis despite the sudden departure of guitarist Glenn Tipton due to Parkinson's disease. That leaves singer Rob Halford and bassist Ian Hill as the band's last original members.

With axe-man Ritchie Blackmore long out of the lineup and organist Jon Lord's death in 2012, Deep Purple is down to singer Ian Gillan, drummer Ian Paice and bassist Roger Glover for its remaining heyday-era members, although the band has counted another guitar god, Steve Morse, among its ranks since the mid-'90s. Morse stood in for Blackmore on stage when the band made it into the Rock and Roll Hall of Fame in 2016.

NICKELBACK (JULY 22): After urging 12,000 fans State Fair goers to put something in their mouth last summer, rowdy rocker Chad Kroeger and his bar-lowering Canadian crew will headline a Saturday night on the TI outdoor stage with Michigan-reared "Footstep" hitmakers Pop Evil for openers. Tickets go on sale Friday at 10 a.m. for $41 via Ticketmaster or the casino's box office.
