"There’s two important things to know about local Denver rock band Mustard: 1. They enjoy playing a heavy brand of retro-rock, that includes tones reminiscent of bands like Kyuss, Fu Manchu, and Blue Cheer. Mustard3 2. They don’t care to write songs or sing about their feelings." " They prefer to play a self-described “comic book rock”, rife with escapist themes based in science fiction, the old west, bank heists, and American muscle cars. Bottom line – Mustard thinks rock music should be fun, and prefers to “entertain” rather than “complain”. And if the smiling faces present at their shows are any indication, mission accomplished."
