Gary Clark Jr. was joined by some special guests during last night’s show at the Central Park SummerStage. The Austin-based bluesman got some help from G. Love for the first two songs of his encore—“In The Evening (When The Sun Goes Down)” and “Shame Shame Shame”—before 11-year-old guitar prodigy Brandon “Taz” Niederauer showed off his chops for the night’s finale, “Bright Lights.”
