One day: That’s all the time it took for the Helio Sequence to record its sixth studio album. The backstory of Brandon Summers and Benjamin Weikel’s latest release revolves around the “20-Song Game,” a challenge among musicians to write 20 songs and record them all in one day. Summer and Weikel were so pleased with their output that they later produced and arranged the songs to create this year’s self-titled LP. It only showcases half of those original songs —too much of a good thing isn’t always a good thing—but the Helio Sequence’s sixth album is just as great as its excellent first and third. A live performance from the duo is the closest you can get to witnessing what it must have been like to spend an entire day creating this wham-bam masterpiece. The Helio Sequence performs with Lost Lander at 7:30 p.m. at the Black Cat, 1811 14th St. NW. $15. (202) 667-4490. blackcatdc.com.
