Capps got his start as a music promoter in Knoxville during the 1970s, where he booked events at the University of Tennessee and off-campus venues.

In 1988 he opened a music club in Knoxville called Ella Guru's, which he closed in 1990 to re-focus his energies on forming AC Entertainment.

Forecastle was selected in 2012 as one of Rolling Stone's "Top 33 Coolest Festivals" and has an annual attendance of over 65,000 fans at Louisville Waterfront Park.

After parting ways with the name Moogfest in 2012, Mountain Oasis Electronic Summit resumed in 2013 with artists like Nine Inch Nails, Bassnectar, Pretty Lights and Neutral Milk Hotel.
