God Street Wine frontman Lo Faber will join New York’s Leroy Justice at Brooklyn Bowl this Saturday. Faber is slated to sit in with the recent Relix On the Verge act throughout their two-set headlining show. The God Street Wine guitarist has collaborated with Leroy Justice in the past, including a memorable 2010 gig at New York’s Sullivan Hall.

The performance will double as a 50th birthday celebration for longtime Relix /Jambands.com friend—and general scene supporter—Mark Wellins. Leroy Justice has also confirmed a mini-tour of Colorado slated for later this month.
