There are more than one band named SEA 1.) SEA - a classic heavy rock group from Denmark. Facebook SEA is Denmark's new hard rock act. Their raw and challenging style is a blend of the classic heavy rock from the giants of the past and their own denim-infused expression. Strong vocals, heavy riffs, catchy choruses, twin guitar soloing and a mission to keep the guitar led rock alive, combine into making the band a huge adrenaline boost into the Danish music scene.
