The self-titled sixth album by The Helio Sequence began with a friendly competition. Several of the duo’s friends within the Portland, Oregon music scene had been playing “The 20-Song Game.” The rules were simple, playful and ambitious: Songwriters would arrive in their studios at prearranged times and spend all day recording 20 complete songs. When they were finished, they’d have a party, listen to the results and talk about the process of simply making music in the moment.
