Mamacken has 3 Glassjaw concerts.

Long Island, NY-based progressive hardcore band Glassjaw was formed by singer Daryl Palumbo and guitarist Justin Beck in 1994, longtime friends who began collaborating as teens. They recorded some demos before releasing the EP "Kiss Kiss Bang Bang" in 1997, and recorded their first full length album "Everything You Ever Wanted To Know About Silence" in 2000 on Roadrunner Records. The record brought the band out of Long Island and into the hands of a dedicated grass-roots following.
