Ryan Allison has 1 Hellyeah concert.

Hellyeah, is an American Groove metal supergroup, consisting of Mudvayne vocalist Chad Gray, former Nothingface guitarist Tom Maxwell, bass player Kyle Sanders (who is the brother of Mastodon bassist and vocalist Troy Sanders), and guitarist Christian Brady. The idea to form a supergroup originated in 2000 on the Tattoo the Earth tour, although plans were constantly put on hold due to scheduling conflicts. The summer of 2006 allowed the band to take the project seriously and record its first album.
