While most folks I'm sure completely gloss over the Amityville Music Hall for its bigger cousin, Revolution, it has its constant share of local bands that have kept the music scene strong for a shit ton of years.
One band I had a chance to shoot there was Cavalry is Us, a rock-punk band based in LI itself. Their music kicks back to earlier 2000's punk/pop; love, life and mistakes wrapped around driving drum beats. Definitely a band born out of Long Island's punk scene with all the trappings that come with a background.
