There are two bands with the name HB. 1) One is a Christian band from Forssa, Finland. Formed in 2002, they started playing rock but have since developed a more massive, heavy metal sound, with orchestral/symphonic backgrounds, and have always had a female lead vocalist. HB has grown to be one of the most popular Christian groups in Finland, and with their first English album Frozen Inside released in 2008, they've also had some attention from abroad.
