In a self-deprecating plea at the Tribeca Film Festival "Breaking the Band" concert at Webster Hall Friday night, Bad Veins singer Benjamin Davis asked the crowd to stick around, because the rest of the acts of the night -- The Republic Tigers, The Virgins, and The Hold Steady -- promised to be better if the crowd didn’t like what the Veins bled. “Well, I guess we’re gonna start now,” he said. “Please don’t leave.” The recipients of the first ever Target Music Maker Award, Bad Veins (Davis, drummer Sebastien Schultz, and a 1973 reel-to-reel named Irene) have learned to be cautious. They’ve performed in New York over 10 times, they were called the “breakout band” of the CMJ music festival, and A&R executives love them. And yet, they can’t seem to get signed.
