OK, maybe there weren’t nine keyboards playing simultaneously onstage during Michael Flynn’s album release show at the Charleston Music Hall in August, but the actual count couldn’t have been far off. Flynn, best known as one-half of the pop duo Slow Runner, released a phenomenal solo album last year called Face in the Cloud, and the recording featured plenty of subtly layered electronics and keyboard riffs — so many, in fact, that we wondered how he would pull it off in a live show. But he made it happen, thanks to a dream team of fellow music scene veterans including Nic Jenkins and Ron Wiltrout, who pulled out all the stops with a dizzying array of sample pads, synthesizers, chimes, and percussion instruments. By the time Flynn busted out the vocoder on “A Love That Bends,” the audience was on the edge of their seats. He was doing it, and we felt privileged to see it happen.
