The formula of reverb-drenched-rock, guitar-drum-vocal, two-man band has proven itself, time and again, to be a successful combination. Acts like the Black Keys and the White Stripes proved that it could be done, and tore their way up the charts while they did so. It is, nevertheless, challenging, blending a careful balance of lo-fi and limited composition with gripping vocals, intricately crafted licks, and thundering percussion, maintaining a smart pop sensibility the entire time. To avoid being pigeonholed, however, as another blues-rock soldier on his quest to the top, it’s important to bend the rules of the genre, throw in some curveballs, and introduce some unique elements to one’s sound, such as the close, soulful cousins that are bluegrass and western folk music. San Francisco duo Two Gallants have done just that, constructing a sonic experience that bears this variety of genres, and yet still stands unique and full of raw passion, which they brought to the Fillmore on Saturday night for their end-of-the-tour hometown show.
