Mastodon endorses Orange amps, i believe.
They where defenitely going for a really "sludgy" sound, and it works IMO. The song has really grown on me. Very catchy, atleast for Mastodon.
It looks like we're getting an album of short, to the point Mastodon-rock! Really looking forward to it!
Only looking at the songtitles im probably looking the most forward to Bedazzled Fingernails (because it sounds br00tal) and Octopus Has No Friends (because of the title
).
