Key of V is a lo-fi experimental folk duo comprised of sisters Erin LaCerra (viola, percussion) and Val LaCerra (guitar, vocals)–who’ve been singing harmonies together since they were toddlers, but officially joined forces as Key of V in 2007. Inspired by an amalgamation of influences including The Beatles, Neutral Milk Hotel, and Bessie Smith, and equipped with acoustic instruments and mics run through effects pedals, Key of V challenges traditional vocals and instrumentation–and the preconception that duos cannot make big sounds. Their 2011 album “Things We Drew From the Treacle Well” wanders through social and relational issues over a backdrop of signature Key of V experimental folk; recorded over a three-year recording period in several spaces and formats, it has been described as moving on from their more experimental album, “Songs in the Key of V” (2007), into the folk realm. Its release sparked their 2011 debut tour with PA friends Clawfoot Slumber. For their 2012 tour Key of V added drummer John Nicholson and synth-player Alex Callenberger (Clawfoot Slumber), and self-released the second of two E.P.s, “Like My E.P” (2012), which explores emotional and social issues with a stylistic nod to acoustic punk. PunkNews.org described Like My E.P‘s messages as “entertaining … as opposed to ramming ideas down listeners’ throats.” Key of V is known for their DIY approach and community organizing, helping host and headline the 3-year running Absorb Williamsport Music Festival, and raising awareness concerning feminist and environmental issues.
