I like my music hard, fast and aggressive, especially when it comes to training.
Pantera fits the bill perfectly.
Normally I would say a cover a of Pantera song is blasphemy, but this is an exception to the rule.
If you're not familiar with the band In This Moment, they rock. Not your typical "chick metal", Maria has a set of pipes on her and she proves it here in a jam session from the TV show "Talking Metal" on the Fuse Network.
Check it out.
If want some kickin' tunes, below Pantera's Greatest hits and In This Moment's latest release.
