“You can’t punch people at a ska show,” my friend Trevor said to me as we waited for the first band to play at the Streetlight Manifesto concert this past Wednesday at Northern Lights in Clifton Park, NY. Which is pretty much true. The overall vibe of that was something along the hippie ideal, treat everyone pretty groovy. Even if I wouldn’t necessarily throw the word groovy around to describe ska. Maybe something more along the lines of hyper relaxing. As kinetic as the synergy of a surprising collective of instruments.
