Rosetta is a four piece from Philadelphia, Pennsylvania, America. The Anaesthete is their fourth LP. Rosetta play a brand of metal that while loosely based in metal stretches out to include elements of post-metal and space rock. These songs are anchored in heavy metal but Rosetta's use of melody, electronics and a piano blast these songs into experimental territory. If Pink Floyd had a child with Neurosis and had it raised by Explosions In The Sky it might sound something like this. If you like your metal both heavy and experimental, Rosetta's The Anaesthete will serve well.
