The Marching Owl Band (aka The MOB or the Blues Band of South Main) is the Rice University "marching band" in the sense that it is the official ensemble that performs during football games, some basketball games, parades, and other public events.
 However, the MOB is not a traditional marching band, but rather a scatter band; members do not march, and some members play non-standard instruments (or no instrument at all).
 For example, in the most recent season these instruments included violins, violas, a cello, electric guitar, electric bass and electric piano.
 Extras known as Show Assistants are also a perennial inclusion in the MOB; these students play no instruments besides the kazoo (or an occasional didgeridoo), but are responsible for constructing and employing props in the half-time shows and acting out any mime or gag bits during performances.
 Rather than wear traditional marching band attire, The MOB instead dons pinstriped three-piece suits, ties, sunglasses, fedoras, and (in the case of Show Assistants) tommy gun props.
 (This attire is an obvious nod to the band's acronym, though in practice falls somewhere between the style of Capone-era mobsters and The Blues Brothers.)
 The group is known for satirical football halftime shows which, as MOB director Chuck Throckmorton says, poke fun at rival universities' sacred cows.
Tesla is an American heavy metal band formed in Sacramento, California in late 1981 by bassist Brian Wheat and guitarist Frank Hannon as "City Kidd".
 Lead vocalist Jeff Keith, drummer Troy Luccketta and guitarist Tommy Skeoch joined them by 1984.

 By 1990, the band started showing signs of wear, with the introduction of drummer, Stefano Pasta taking the throne for Luccketta for a brief period until his own departure for personal reasons.
 In 1996, the band disbanded, with members devoting themselves to solo projects.
 In 2000, they reformed, but Tommy Skeoch departed the band in 2006 due to substance abuse, and was replaced by Dave Rude.
 They have sold 14 million albums in the United States.
Tommy Conwell is a US guitarist, songwriter and performer.

 The original band, consisting of Tommy Conwell (guitar, vocals), Paul Slivka (stand-up bass) and Jimmy Hannum (drums), was known for its raw, high-energy live performances which included many classic blues and rock standards.
 such as "Hideaway" by Freddie King, "Rumble" by Link Wray, "Time Has Come Today" by The Chambers Brothers and "Downtown Train" by Tom Waits, together with several original songs, some of which appeared on the debut album, "Walkin' on the Water".
 Other signature tracks such as "Demolition Derby", which many felt exemplified the band's raw three-piece sound, were abandoned following the shift of the band's sound following the addition of two members, keyboard player Rob Miller and Chris Day on guitar.
