Brian Helicopter: Brian Helicopter is the stage name of Gareth Holder (born 27 June 1958, Leamington Spa), an English musician, based in the United States.  He is best known for playing bass guitar for the UK punk rock band The Shapes.  He also played for many other bands, the most notable being the NWOBHM bands Rogue Male and HellsBelles.  For a short time in the early 1980s, he was also a member of British R&B band The Mosquitos, with guitarist Steve Walwyn of Dr. Feelgood and Eddie and the Hot Rods, and can be seen on the cover of The Mosquitos only single "Somethin' Outta Nothin'".  A prolific session player, he appears both credited and uncreditied on many releases throughout the 1980s and early 1990s under both his real and stage name.  He was one of the first bassists in the nascent UK punk scene to adopt the Rickenbacker bass guitar which he still uses to this day.  He was also one of the first bass guitarists in the world to use Trace Elliot amplification.  His bass playing style is characterized by a very fast precise pick attack, and fast runs.  Unusually for a bass guitarist, he sometimes utilizes an overhand tapping technique more common to six string players.  He continues to play professionally, reverting between his real name and his stage name as the fancy takes him.  He is also a professional skydiving coach and instructor, currently holding seven world records in the sport.  He can be seen in an episode of MythBusters aired on the Discovery Channel taking presenter Kari Byron skydiving whilst testing the falling airplane blue ice myth.  He is also a vegetarian.  He can be seen in the independent film Six Sex Scenes and a Murder, in the role of the bounty hunter.  He currently resides in California, where he plays bass for the San Francisco Bay Area band Ghosthookers.
