When the owners of the Monarch Theatre stated they wanted the downtown Phoenix venue to become one of the premier forums for electronic dance music in the Valley, they weren't screwing around. In the four weeks since the joint debuted, it's featured such top-shelf EDM tastemakers as New York trance god Victor Dinaire and Detroit house music mensch Anthony Attalla. Things will be just as star-studded during the grand opening of the Monarch Theatre, 122 East Washington Street, this weekend. Some of the folks behind the ultra-popular Sticky Fingers are bringing in California-based electro wunderkinds Tommy Noble (who have opened for Dirtyphonics, Tiësto, and Porter Robinson) on Thursday, May 24, for a special performance. Prince$$ and 2ToneDisco also are scheduled to appear. Doors open at 10 p.m. Admission is $5. See www.ticketleap.com. Valley EDM promoters Relentless Beats then will debut their new weekly affair on Saturday, May 25, with a performance by Grammy-nominated electronica songstress Nadia Ali and a spin session by Turner and Heit. Doors are at 9 p.m. Tickets are $10 to $20. Visit www.relentlessbeats.com.
