Robert Bernard Andrew "Bobby" Gillespie (born 22 June 1962) is a Scottish musician and singer-songwriter.
 He is the lead singer and founding member of the alternative rock band, Primal Scream.
 He was also the drummer for The Jesus and Mary Chain in the mid-1980s.
"Velocity Girl" is a song by British alternative rock band Primal Scream, originally released as the B-side to their second single, "Crystal Crescent", in 1986.
 Shortly preceding its release, Primal Scream’s frontman, Bobby Gillespie, left his post as the drummer of The Jesus and Mary Chain, recording only one album with them, the influential noise pop release "Psychocandy" (1985).
 Disentangled from their major label "whirlwind", he resumed activity with the lesser known Primal Scream, proceeding to, as "Pitchfork Media" later described it, "reduce the pop song to its subatomic essence: quick, breezy, quirky, and above all, exquisitely small" with "Velocity Girl".
Murray Dalglish was the original drummer for The Jesus and Mary Chain from their formation in early 1984 until November 1984 when he was replaced by Bobby Gillespie.
 Aged 16 when he joined the band, Dalglish played a two-piece drum kit, which he did whilst standing up; this style would later be carried on in Gillespie's playing.
 His drumming can be heard on the band's first single "Upside Down", along with its B-side, the Syd Barrett cover "Vegetable Man".
 He was reportedly kicked out of the band as his father demanded that Dalglish be given more money, despite the fact that the band at the time was making little, if any, money at all.
Bow Down to the Exit Sign is a studio album by David Holmes, released in 2000.
 It features contributions from Bobby Gillespie, Sean Gullette, Jon Spencer, Martina Topley-Bird and Carl Hancock Rux.
 The song "69 Police" features during the closing scene of the 2001 remake of "Ocean's Eleven", and was included in the soundtrack.
Darklands is the second album by Scottish alternative rock band The Jesus and Mary Chain.
 Unlike their previous album, drum machines were used in place of drummer Bobby Gillespie, who had left to pursue a successful career as the frontman with Primal Scream.
 The album marks a turning point in the band's music, going from the noise-pop of "Psychocandy" to a more melodic indie/alternative sound.
