Ace Frehley may not have technically come from space, but Kiss' longtime guitarist has proven to be their hardest-rocking alumnus over the years—at least judging from albums released under both his own name and Frehley's Comet since the late '70s. In songs that are down-to-earth yet catchy and playfully tossed-off, he splashes unassuming everyman vocals atop an infectious New York groove. His Les Paul-cranking solo work has also been reliably influential, inspiring axmen from Anthrax, Guns N' Roses and Pantera. Want metal to lift your spirits while it bangs your head? Look no further.
