The newly-established Palmetto Acoustic group will present the first of the monthly “Open Mic Challenge” at the West Ashley Muddy Waters on Wed, May 13. Over the last year, Palmetto Acoustic has presented free acoustic showcases every other week at this venue series, highlighting a mix of local and visiting singer/songwriters performing original music.

Modeled after open mic events held at some of the top listening rooms in Atlanta’s Eddie’s Attic and Boston’s Lizard Lounge, each performer gets a 10-minute slot, and the top three will get an encore set at the end of the night to determine the winner. Guest judges will evaluate the sets with five criteria in mind: songwriting, vocal performance, playing ability, stage presence, and audience response. Local songwriter and guitarist Aaron Levy (of White Rhino) will host.

Advance sign-ups at Players may only be signed up for one future Monday time slot at a time. Each act must be limited to three players per act. No guitar effects or amps are allowed. No full drum kits. Performers must check in for their slot 30 minutes prior to their scheduled playing time.

Monthly winners will receive a cash prize and a spot in the bi-annual winners circle event held in November. Start time is 7 p.m.
