One of my favourite metal bands of the last few years has been Mastodon. Their first three albums showed their evolution from violently heavy sludge metal into a more progressive metal band. Album number four, Crack The Skye, was the album Mastodon fans were waiting for them to make and it’s only $5 right now.

Written largely by guitarist Brent Hinds, while recovering from an altercation with System Of A Down’s Shavo Odadjian which left Hinds in a coma, it is a swirling, dream-like but intermittently heavy album.

Until 11:59 PST October 31, 2011, you can get this brilliant album for only $5 as part of Amazon’s awesome $5 MP3 Album Deal, which includes 100 albums at the discounted price.
