In 1996, College of Music student Phil Johnson founded the Accafellas at Michigan State University. In 1997, the newfound group released their debut album, Accafellas Volume I, which is currently out of print. In 1998, at the University of Michigan’s Monsters of A Cappella concert, the relatively new Accafellas received a standing ovation from a pro-wolverine crowd. In 2000, the Accafellas released Accafellas Volume II. In 2004, the Accafellas released Accafellas Volume III, a much more polished effort which would serve as a great influence on future Accafellas releases. In 2006, the Accafellas released "Accafellas Volume IV". Their version of the song "You and I Both" by Jason Mraz appeared on Varsity Vocals' Best of College a Cappella compilation that same year. In 2009, the Accafellas released "Accafellas Volume V". The album was recorded at Ryan Wert's Elm Street Recording Studio in Lansing, MI. Ryan Wert claimed that Volume V was "The most ambitious of the CD's (he's) recorded."

On June 11, 2010, the Accafellas performed the song "Would You Go with Me" with Josh Turner at his fan club party before the CMA Music Festival

In addition, The Accafellas have competed multiple times in the International Championship for Collegiate Acapella  (ICCA). They have won awards at these competitions for their arrangements and soloists, most notably advancing to the regional semi-finals in 2008, 2013, and 2015. In the 2012 ICCA Quarterfinals, the Accafellas received two awards: Best Soloist (Joe Caigoy for "Without You") and Best Arrangment (Jake Przybyla, Duncan Cooper and Richard Hofmeister for "Clocks"). In 2015, The Accafellas placed 2nd in their ICCA Regional Quarterfinal sending them to the Sectional Semifinals in Ann Arbor. Their set included Hozier's "Take Me to Church" (Solo: Connor Ralph), Sam Smith's "Lay Me Down" (Solo: Andrew Lee), and Fall Out Boy's "Centuries" (Solo: Brad Larsen). In 2015, they took third place in the quarterfinals. There setlist consisted of a Motown Medley ("I Want You Back", "Please Mrs. Postman", "Superstition", "Easy", "Tracks of my Tears", "My Girl"), Allen Stone's "Satisfaction", and The Weeknd's "In The Night".

The Fellas perform all over campus and throughout the Midwest. The group has previously performed at the White House and at the Michigan Governor's Mansion. They would love to perform at your next event, so book the Fellas!
