Although Mastodon's new album Crack The Skye is a conceptual piece like their previous releases, the record's sound is not as experimental as before and will actually reach more people and develop a wider basis of fans. According to Dailor Mastodon wanted to stick to elements as air was the element of the previous record. The element of the new record is ether, which is what the soul is made of.
