Anthrax recently released its For All Kings vinyl box set, which included the entire album on 7" records, and covers of Kansas's "Carry On Wayward Son" and The White Stripes's "Black Math." You can check out the Kansas cover below, and don't even try to act like you don't know every note and lyric to the song – you do and so does everyone else.
As for the cover, it's awesome! The guitar solos are very Anthrax, but by and large the band cranked out an awesome rendition of a classic.
