Blue Man Group started in 1987 as a performance art concept by guys who also harbored rock 'n' roll dreams. It has grown into an institution that has ongoing shows in Boston, Chicago, Las Vegas, New York and Berlin. As of October, Blue Man Group now also has a Christmas EP, Overjoy to the World. Today Blue Man composer Jeff Turlik and performer Bhurin Sead talk about all things Blue Man Group including how songs are written and recorded for a band known for playing percussion instruments made of PVC, and how holiday music fits into their shows.
