The Helio Sequence is an indie rock band signed to label Sub Pop. The band was formed in 1999 in Beaverton, Oregon, a suburb of Portland, Oregon, and consists of Brandon Summers on guitar and vocals and Benjamin Weikel, who has also played for Modest Mouse, on keyboards and drums. The band produces an eccentric brand of electronica-tinged indie rock. To date, they have released two albums on Sub Pop, two on Portland-based label Cavity Search and a self-released EP. Their fourth album, entitled Keep Your Eyes Ahead, was released on January 29, 2008, by Sub Pop. The band's sound evolved on Keep Your Eyes Ahead, due in part to Summers damaging his vocal cords and then relearning to sing .
