It's easy to talk to Peter Resendiz, frontman of Phoenix's Sad Dance Party, and forget that he's just 20 years old — or that his band have only been around for a couple of years. Part of that ease is Resendiz's blend of charm and commitment, the kind of musician you'd follow even through a lengthy goth phase. With Resendiz as their screaming, beating heart, SDP make deeply expressive music, squeezing every intense, overwhelming emotion possible into two-minute punk songs. Last year's Spontaneous Human Combustion felt like an achievement in balancing earworm songwriting with deeply visceral displays of humanity, and yet the band already have moved onward and upward. Subsequent singles like "Older, Sadder" track SDP toward new, more streamlined territories that only extend their basic shelf life. And all that's before word one of their frequent touring, collaborations with other local bands, and December's Pleasure Planet festival. SDP are a true Phoenix band, typifying the city's restless energy and knack for trail-blazing. Now, everybody dance away all your deepest, darkest feelings.
