Seeing bands in bars, clubs & small venues has been one of the common threads of my life since I was 15 & went to see the Circle Jerks in the basement of the Cuban Club.
To give a little back, I'm building this site to aggregate bands that are being displaced from touring to highlight merch to help offset the lost revenue.
