The Bad Penny (beta)

Metallica, the biggest metal band ever; and Mastodon, one of the best metal bands of this century, share a lot in common.

For starters, Mastodon started publicly crediting Metallica as major influence shortly after the Atlanta crew became a band in 2000. Six years later, Mastodon covered Metallica’s instrumental classic “Orion” for a tribute album tied to the 20th anniversary celebration of Metallica’s Master of Puppets.

James, Lars and the gang returned the favor a couple of years after that. The thrash gods gave the Atlanta sludge-rockers a huge break by crowning them as the openers for two of Metallica’s European tours. For good measure, 2009’s Guitar Hero: Metallica featured Mastodon’s “Blood and Thunder” as one of its playable tracks.

But the common bonds don’t stop there. There’s a truly uncanny coincidence in two songs by the metal bands, both of which deserve to sit on the Iron Throne. The numbers will be familiar to fans: “Welcome Home (Sanitarium),” from Metallica’s best (or second-best) record, 1986’s Master of Puppets; and “Megalodon,” a gem of a track from Mastodon’s breakthrough record, 2004’s Leviathan.
