Soundgarden

It's subtle, but telling, that the cover of Audioslave's eponymous debut is designed by Storm Thorgerson, the artist behind Pink Floyd's greatest album sleeves. Thorgerson, along with Roger Dean, epitomized the look of the '70s, the era of supergroups, which is precisely what Audioslave is - a meeting of Rage Against the Machine, minus Zack de la Rocha, with former Soundgarden vocalist Chris Cornell. Though both bands were leading lights of alt-metal in the '90s, the two came from totally separate vantage points: Rage Against the Machine was fearlessly modern, addressing contemporary politics over Tom Morello's hip-hop-influenced guitar, while Soundgarden dredged up '70s metal fueled with the spirit of punk…

The Pretty Reckless gave rock ‘n’ roll the jumpstart it needed for a new generation, but they did so entirely on their own terms. Since 2008, they have emerged as the rare force of nature who can appear in INTERVIEW Magazine, Nylon, ELLE, Good Morning America and Entertainment Tonight — and share a stage with Guns N’ Roses and Soundgarden. Joined by late producer Kato Khandwala, they fanned this flame on Light Me Up [2010] and Going To Hell [2014]. The latter housed three #1 smashes—the platinum-certified “Heaven Knows” (the biggest rock song of 2014), “Fucked Up World,” and “Follow Me Down.

There's no denying Australian heavy rock trio Wolfmother has been raised on rock – specifically, raised on '70s rock. Problem is, from all appearances on their eponymous debut, they made their journey into the past via the twin gateway drugs of the White Stripes and Queens of the Stone Age, and once they dug back to the original Zeppelin and Sabbath texts (stopping along the way for some Soundgarden discs and maybe, for lyrical inspiration, Yes and Rush), they indulged so much it screwed with their sense of aesthetics.
