20. Helmet, 'Betty'
Helmet made rhythmically complex, steely-riffed alterna-metal that punished your body from odd angles (when forming, they placed an ad in The Village Voice searching for an "asexual bass player"). Touted as the "next Nirvana," their 1992's Interscope debut Meantime made the New Yorkers the most successful band to come out of the thuggy, noise-cretin Amphetamine Reptile scene; and while Betty wasn't as immediately exciting as its predecessor, it spun their sound into jazz, blues and improv, challenging their art-jock fanbase ("Beautiful Love" begins as a Brazilian guitar piece then explodes into abstract free-rock jamming). They still managed to score a minor modern rock hit with "Milquetoast" and deliver one of the year's truly crushing major label rock albums. Jon Dolan
