Lewis Brian Hopkins Jones (28 February 1942 – 3 July 1969), known as Brian Jones, was an English musician and a founding member of The Rolling Stones.
His main instruments were the guitar and the harmonica, but he played a wide variety of other instruments. His innovative use of traditional or folk instruments, such as the sitar and marimba, was integral to the changing sound of the band. He was originally the leader of the group, but Mick Jagger and Keith Richards soon overshadowed him, especially after they became a successful songwriting team. Jones developed a serious substance abuse problem over the years and his role in the band steadily diminished. He left the Rolling Stones in June 1969 to be replaced by guitarist Mick Taylor; Jones died less than a month later in his own swimming pool.
