H20 has got that P.M.A. The legendary NYC hardcore punk band, known for their high energy anthems, pile-on singalongs, and absolutely bananas live shows, have been kicking around for over 20 years, spreading the gospel of “positive mental attitude” wherever they go.

Led by outspoken vocalist Toby Morse, it’s no wonder H20 are celebrated in the scene. They’re a true hardcore band in every sense of the word, fueled by strong messages and strong songwriting. That they connect with kids and adults alike is a testament to their fortitude and belief in the power of hardcore music.

Tonight, along with Angel Dust, featuring Justice of Trapped Under Ice fame, H20 will be playing at the Studio in the upstairs of Waiting Room (6:30pm, $17). Also on the bill is Give and Buffalo’s own, the Barksdales, who recently released the excellent In Our Hands EP (check it out on bandcamp or buy it at the show tonight).

Do yourself a favor; if you have never heard H20 peep the video below for their classic “Family Tree,” then head to the show tonight.
