There is more than one band with the name Sand, at least ten:
1.)The krautrock band from lower Saxony, Germany, that released one album, Golem, in 1972. The album was produced by famed German producer/musician Klaus Schulze, and is known for its heavily psychedelic, synthesizer-based sound, although it does have many moments of somber acoustic melodies.
2.) A Japanese metalcore/beatdown band (Sandjp). They released a couple of split-cd´s in Japan. They released an album in 2008 called Nuthin but a bitter mouth and have just recently released a CD called Spit on Authority in 2013
3.) The Indie (Rock) band from Germany consisting of Sebastian Lohse (known as Robin Sohn, the former vocalist of Letzte Instanz) and Frieder Zimmermann. Founded in 2001 they released their debut album Winterlieder in September 2005.
