Before they dethroned Michael Jackson atop the Billboard chart with Nevermind, Nirvana were an unassuming, unpolished, underground rock band from Aberdeen, Washington, welding primitive noise-punk to nascent pop hooks. Their pre-Grohl debut features two drummers Chad Channing and the Melvins Dale Crover across its 11 tracks, which veer deliriously from more accessible cuts like the Shocking Blue cover and Sub Pop single Love Buzz to teeth-gnashing ragers like Negative Creep. Kurt Cobains genius was still taking shape, but its paradigm-shifting potential shines through.
