This double bill may seem a bit odd upon first glance. Twenty-seven-year-old Demarco is still young and carefree, gleefully strumming his guitar, writing quirky tunes and occasionally flying off the rails during his live shows. The Lips, on the other hand, are seasoned pros who have spent decades touring and building a fan base hooked on their kaleidoscopic concept albums and whacked-out exhibitions of psychedelia. Look closer, though, and it becomes easier to see the connections. Demarco and Wayne Coyne follow the muse where it takes them. Their frequent over-the-top antics mask heartfelt and emotional tales of grief, alienation and existential doubt. While Demarco funnels these feelings through laconic, ’80s-tinged guitar, Coyne and his longtime collaborators focus on the lyrical content. At heart, Demarco and Coyne are both weird and unpredictable dudes, which makes for good theater. While it's unclear if they'll team up for a few tunes Saturday night, they have a collaborative EP coming out soon, which, given their varying sonic approaches, should make for an interesting listen.
