When Mann called to recommend Tommy Mars ("At midnight, the only time when you could reach Frank by phone"[This quote needs a citation]), Zappa invited him to come to his house.

Until mid-2014, Mann was a member of The Band From Utopia which had featured many Zappa alumni such as Robert Martin, Chad Wackerman, Albert Wing, Tom Fowler, Ray White and Ralph Humphrey over the years.

In 2013, Mann began performing on percussion and electronics with The Z3, an organ, guitar and drums trio that adapts Zappa music to the Hammond organ-centered jazz-funk tradition.

Mann joined Northeast blugrasstafarian jam band Desert Rain for their set at the Wormtown Music Festival in late 2015.

[2] Mann performances can be seen in the Zappa films Baby Snakes, Dub Room Special & Video From Hell.
