Joseph Steinhardt and Zach Gajewski were attending a Boston college when they founded Don Giovanni Records in 2004. The idea was to put out hardcore music they liked, with a specialization, according to Steinhardt, in “releasing music from New Brunswick, N.J., and the surrounding area (including Brooklyn and New York City), and attempting to level the playing field between those bands and bands on larger labels.” But these guys don’t just put out music—they also bring it to you. And this weekend, they’re bringing you plenty over two nights at Music Hall of Williamsburg. Tonight, Laura Stevenson (above, playing “Master of Art”) headlines alongside Jeffrey Lewis, Waxahatchee, Lemuria and Hilly Eye. And tomorrow you can see another packed lineup with Screaming Females, Black Wine, Stormshadow, Home Blitz and Shellshag.
