Philly rock ‘n’ rollers Lightninging and Univox take the stage tonight at MilkBoy Philly in support of Brooklyn guitar addicts Fang Island. Lightning is a five-piece group in which all the members, with the exception of their drummer, switch instruments in between songs throughout their sets. Their tracks are rooted in the traditional indie rock format, but often expand into extended musical journeys complete with vocal harmonies, keyboards and trumpets. Univox combines fuzzy garage rock with the vocal harmonies of 60s girl groups adding a sense of harmonic texture that is usually missing from guitar bands. Back in February, the quartet recorded a 5-song live performance for XPN which included the first live performances of the 13th Floor Elevators-esque “I’m Better Off By Myself” and the noisy punk song “Eat Drink Eat Drink Sleep Sleep Sleep.” Fans can look forwarded to hearing these two tracks this evening and hopefully some more new jams that they’ve concocted in their recently built home studio.
