In mid-2015 Kase was playing bass in Sheffield rock band, Riker.
Sophie was performing around the country as a solo act.
Following a successful gig filling in for Riker in the absence of their vocalist, Sophie was asked to join the group full time, however, it was not to be. Riker was short-lived and, sadly, soon fell apart.

From the pieces, a duo - Felix Culpa - was born.

Felix Culpa are Sophie Mapplebeck (vocals, guitar, percussion) and Kase Allen (bass, guitar, backing vocals). Upbeat sets combining classic songs with unique arrangements and more than a few curveballs thrown in, we aim to get any crowd singing along, saying "I haven't heard this for ages!" and coming back time and again.
