Epsilon is a Canadian vocal group based out of Edmonton, Alberta.  The group consists of six members (Caleb Nelson, Bernard Quilala, Brett Ludwig, Tyler Smith, Kyle Carter, and Andrew Malcolm) with extensive backgrounds in rock, pop, jazz, classical, and choral music. Epsilon is renowned for its exceptional a cappella singing - tight harmonies, seamless phrasing, thrilling lead-solos, and intricate beat-boxing. Their love for singing and their ability to create a soundscape with their voices continues to inspire audiences both young and old.

The group’s repertoire ranges from the upbeat stylings of rock and pop music to the complex nuances of jazz, drawing influence from Boyz II Men, Take 6, Michael Jackson and many others.

Epsilon has performed with many organizations, including the Edmonton Symphony Orchestra at their “First Night at the Pops” concert, and with Pro Coro Canada at various concerts. They have also performed as guest artists at various festivals including the Edmonton Cantando Festival in 2009, and ChoralFest North alongside the talented Contemporary Vocal Ensemble "Sixth Wave". In 2008 they competed in David Foster's Star Search, placing as finalists and performing at David Foster's prestigious charity auction.

Recognizing the importance of encouraging choral and vocal education, Epsilon has performed and presented workshops for many high schools and community groups, including the Men of Note from Grande Prairie, Take Note from Red Deer, the Elk Island Honour Choirs.
