After packing the Varsity Theater in March and making a good impression at last year's Basilica Block Party, Las Vegas rockers Imagine Dragons will make a big leap to Roy Wilkins Auditorium on Sept. 30. Tickets will be $32.50 and $42.50 and go on sale Friday through Ticketmaster or at the Wilkins box office. The quartet landed the radio hit "It's Time" last year and are doing even better now with the aptly named follow-up, "Radioactive."

Other concert news issued today:

*One of two bands with original members performing Black Flag songs on tour this year, the group simply known as Flag will hit First Avenue on Sept. 13. That's the one featuring pre-Henry Rollins singers Keith Morris (later of the Circle Jerks and OFF!) and Dez Cadena along with drummer Bill Stevenson (future Descendents) and bassist Chuck Dukowski. The $30 tickets go on sale Friday at noon through eTix and First Ave outlets. Morris was also part of the great Black Flag tribute tour put on by the Rollins Band in 2002 as a benefit for the West Memphis 3. Black Flag guitarist and ringleader Greg Ginn is also now touring with a makeshift lineup of the legendary Los Angeles punk band, but no local date has been set.

*The Cult will mark the 25th anniversary of its "Electric" by performing the whole thing at the Varsity Theater on Aug. 5. That's the record that paired them with a hip-hop producer named Rick Rubin and sent them down a more metallic path with the radio hits "Love Removal Machine" and "Lil' Devil." Tickets will be $35 and $50 and go on sale Friday at 10 a.m. through Ticketfly.com, the Electric Fetus or Loring Pasta Bar. The British rockers also performed the prior album, "Love," in its entirety on tour two years ago.

*Sick Puppies had to postpone its show tonight at Mill City Nights due to "vehicular failure." A makeup date is expected in the fall, and fans are being told to hang onto tickets in the meantime.
