There are at least 2 bands/artists with the name Vamps. 1) VAMPS is a Japanese rock unit by Hyde (lead vocalist of L'Arc~en~Ciel) and K.A.Z (guitarist of Oblivion Dust, hide with Spread Beaver and Spin Aqua). HYDE and K.A.Z have been working together since HYDE's third solo album FAITH, which was released in 2006. In early spring 2008, they announced the name-change for HYDE's solo project - and officially formed a band. One of the reasons being to give more credit to K.A.Z for his work. Thus VAMPS was born.
