Versa (stylized as VERSA) are an American rock duo formed in Port St. Lucie, Florida in 2006, as VersaEmerge. The group consists of Blake Harnage (guitar, vocals, and programming) and Sierra Kay (lead vocals). Versa had a revolving line-up, their most prolific being with bassist Devin Ingelido, who was a member from 2007 until 2011.
Following self-releases, the band signed with record label Fueled by Ramen in late 2008 and released VersaEmerge EP in 2009, and their full-length debut Fixed at Zero (2010) met with positive reviews from alternative critics. The album didn't enter the Billboard 200 chart, but it ranked third on the Billboard Top Heatseekers. After changing their name to Versa, the duo self-released the EP Neon on January 21, 2014.
While the band is considered part of the emo pop scene and compared to other emo female-fronted bands, Versa's music style includes experimental rock, space rock and electronic rock, as being influenced by artist Björk and band Muse.
