Deer Tick does a pretty good job of subverting your expectations. Judging from the album cover of their first full-length album, “War Elephant,” which includes nothing less than the band members sitting on a sand dune in front of two women in bikinis holding a shotgun and an AK-47, you might not expect the mellow fingerpicked guitars that follow. Moreover, after hearing Deer Tick’s infectious blend of tender folk and rollicking roots rock, you might not expect it to be something you could mosh to. Nonetheless, that’s exactly what we did at Deer Tick’s March 3 show at The Haunt. The night began with comedian Solomon Georgio taking us through his life as an African immigrant and “professional homosexual,” interweaving narratives of childhood bullies with social commentary on racism and homophobia.
