On the eve of Independence Day and a three-day weekend, the Black Cat hosts two local rock acts that provide the soundtrack to your daydreams. The Sea Life headlines in support of its third release, Transitions, a four-song EP recorded, like their 2012 full-length In Basements, below ground with Tommy Sherrod of Full Glass Records. The shoegaze band plays light, breathy songs, and the title track from its new release deals with similarly ephemeral things, hazily recollecting seasons and memories. Opening for the Sea Life is Humble Fire, a female-fronted indie-rock band that balances delicate lyrics on snarling guitars. The self-described dream rockers’ “Battle Ready,” off their December 2013 debut, The Great Resolve, captures their sound: precise, reverberating vocals blended with a pounding drum and bass line. How better to celebrate America? The Sea Life performs with Humble Fire and Sun Club at 8 p.m. at the Black Cat Backstage, 1811 14th St. NW. $10. (202) 667-4490. blackcatdc.com.
