Black Sixteen was formed in London, UK in late 2010 by songwriter Amir Khan (formerly of grunge-rockers 'Unusual Pets') on guitar, accompanied by Matt Burn on the drums, under the temporary moniker of 'Rain Hits Concrete'. The current line-up was completed with the addition of Alex Brock (previously in 'The Moscow Undergound') on bass and Laura Sepp (from Estonian metal outfit 'Label Of Guilt') on keyboards in early 2011.
Soundgarden is a Seattle rock band who helped to define the sound that came to be called grunge. Despite starting years earlier, and having a sound that more closely resembled Black Sabbath or Led Zeppelin than their contemporaries, they are usually considered one of the "big four" of the '90s Seattle grunge bands, along with Alice in Chains, Nirvana and Pearl Jam. The band was formed in 1984 by Chris Cornell (vocals, and originally drums) and Hiro Yamamoto (bass), to be joined later by Kim Thayil (guitar) and Scott Sundquist (drums).
