10 Huge Rock & Metal Bands Glastonbury Couldn't Handle

4. Mastodon

They've appeared on Radio 1 and Jools Holland, normally the perfect warm-up for a standard slot at Glastonbury, but could the precious ears that make their way to Worth Farm every summer really handle the metal concoction that blends a number of sub-genres such as progressive, sludge, experimental, stoner and groove into one huge sound? Probably not. Despite lowering the sheer mass volumes of metal since they first started out back in 2000 with their debut-album Remission, Mastodon would bring with them a cult following of fans craving for some serious thrashing that the Pyramid stage sound system wouldn't be able to handle. The last thing the organisers need is a load of metal heads starved of their thrashing, right? And don't tell me that they wouldn't HAVE to play the top stage, because this is Mastodon we're talking about. This band have won album of the year awards, Grammy nominations and featured in the top 10 on the Billboard 200 chart. The only other thing issue holding them back from tearing Glasto a new one is that their bears are too awesome. No seriously. There is only one man who can take the best beard crown at the festival and that is held by Seasick Steve, sorry guys.
