R is for Rocket, the quartet's remarkable debut album, is a joyride through sonic terrain that is gloriously loud, anthemic, bombastic and beautiful, with instantly captivating songs that achieve the rare feat of evoking nostalgia while sounding completely new. The band's jagged, fuzzed-out sound has antecedents in '90s guitar bands like Sonic Youth and My Bloody Valentine, but Rocket are doing something uniquely their own with those touchstones. It's no wonder they are widely considered one of the most promising guitar-forward bands of their generation.
