Whitesnake are an English hard rock band formed in London in 1978. The group was originally put together as the backing band for singer David Coverdale, who had recently left Deep Purple. Though the band quickly developed into their own entity, Coverdale is the only constant member throughout their history.

Hard rock or heavy rock is a heavier subgenre of rock music typified by aggressive vocals and distorted electric guitars. Hard rock began in the mid-1960s with the garage, psychedelic and blues rock movements. Some of the earliest hard rock music was produced by the Kinks, the Who, the Rolling Stones, Cream, Vanilla Fudge, and the Jimi Hendrix Experience. In the late 1960s, bands such as Blue Cheer, the Jeff Beck Group, Iron Butterfly, Led Zeppelin, Golden Earring, Steppenwolf, and Deep Purple also produced hard rock.
