Soft-spoken by nature, south Florida-bred Roosevelt Collier does his hollering on the steel guitar. Seated front and center, the “sacred steel” frontman with the Lee Boys leaves an indelible mark on listeners, flooring audiences with his lightning-fast slide work. A regular “Artist at Large” at festivals, the sit-in virtuoso has built a reputation for collaborating with some of the industry’s most respected artists of all genres, from the Allman Brothers and Umphrey McGee, Del McCoury Band and Dumpstaphunk. His new side-project, the Roosevelt Collier Trio, features Mofro drummer Anthony Cole and Shak Nasti bassist Matt Lapham — a powerhouse rhythm section, creating a filthy groove for Roosevelt’s slide to sing like James Brown and shred like Jimi Hendrix. No matter the context, when Roosevelt takes the stage, the ear-to-ear grins canâ€™t help but be contagious.2011-2013 collaborations include: Allman Brothers, ALO, Anders Osborne, Bobby Lee Rodgers, Break Science, Col.
