Pelican is a
Irepress (pronounced ear-press) is a 5-piece self-proclaimed disco metal band from Massachusetts. However hilarious disco metal may sound, I don't think they're it. Similar to Pelican above, Irepress's sound is a very heavy "sludge" type of post-metal. They are an extremely progressive band (they even have a part or two that actually does sound like disco), and their musicianship is very technical.
I hope Pelican managed to get away from that singer this time!
