Phase is a UK-based rock band formed in Larissa, Greece in 2003. It was founded by Thanos Grigoriou, who was performing and recording with various members until the line-up was completed in 2011, with the addition of Damos Harharidis and Vasilis Liapis. They debuted with their digital single Perdition under Microsoft's "Playlist Seven" co-promotion campaign for the release of Windows 7, which was followed by two full-length albums In Consequence and the Wait.
