A number of dates on Rihanna's Last Girl on Earth tour, meanwhile, have been canceled reportedly due to scheduling conflicts, including her upcoming show with Ke$ha this Thursday, July 15 at Comfort Dental Amphitheatre. Rolling Stone magazine reports that the cancellations may have been due to soft sales. Refunds are available at point of purchase.

Good thing you waited. Starting today at 10 a.m., you can purchase single day advance tickets for $99.50 (or pick up single day VIP for $225), with no additional charges or fees at TicketHorse.com.

Superstar DJ Keoki, who's done his share of gigs in Denver, recently moved back from Los Angeles to Golden. With some help from his business partner John Bogard, he just opened Club Exile at 753 Santa Fe Drive. The space has been renovated, but as of right now, just the first level is open. Keoki plans to open the second level at some point with a rooftop for parties during the summer. Keoki, OhmStyles, and Dolly Madeline hold court on the gay-friendly Fetish Fridays, where club-goers can wear their favorite fetish gear. On Tuesdays, meanwhile, Keoki, LLbishop, Tharin Roberts and DJ smyl:e are slated to spin on Dirty Mutant Tuesdays.

Between fronting 16 Horsepower and Wovenhand, David Eugene Edwards has spent a fair amount of time touring Europe.

Oh, and did we mention, it's Vegas, baby! Vegas!

Oh, and speaking of reunions, we've received word that these dudes are getting back together one more time for old time's sake.

If you missed the band at Denver Fest for its last reunion, here's your chance to see a landmark Denver punk band in the company of the Gamits, another renown institution back together again, who will be releasing their eagerly anticipated new disc, The Halves and Half Knots, that same night at the Gothic Theatre, on Saturday, September 4. Tickets are $12.50 and on sale now.
