An A unit, in railroad terminology, is a locomotive (generally a diesel or electric locomotive) equipped with a driving cab, or crew compartment, and the control system to control other locomotives in a multiple unit, and therefore able to be the lead unit in a consist of several locomotives controlled from a single position. This terminology is generally used in North America, since only there was it commonplace to build B units—cabless locomotive units which normally could not lead a train.

Typical driving cab features, and therefore A unit features, include windshields, rectangular side windows, crew seats, heating, and sometimes, radios, air conditioning and toilets. B units always lack all of these features, except that some EMD F-units have an extra porthole-style side window(s) for a hostler (an employee permitted to move a locomotive in a yard only — not on the road).

This terminology has fallen out of use for newer locomotives, since it only really applied to the cab unit style of locomotive. Thus, the term cab unit is used only when an A unit has a carbody design. Hood unit "road switcher" types were generally equipped with driving cabs and the term "A unit" was not generally applied to them, although the rare cabless road switchers were still called B units.

Luke Wyland is the multi-instrumentalist behind Portland, Oregon experimental pop group AU. Wyland started AU in 2005 while completing a degree at the Massachusetts College of Art. He later moved cross-country to Portland, Oregon and established a base in its music community. Now a working live band, AU features an ever-changing roster of players, recently including Jonathan Sielaff (Parenthetical Girls, Nick Jaina) on guitar, clarinets and saw; and Dana Valatka (Jackie-O_Motherfucker, Mustaphamond) on drums. Contributors to AU's recordings included Mark Kaylor (Hamor of Hathor, CexFucx), Becky Dawson (Saw Whet, Ah Holly Fam’ly), and Sarah Winchester (A Weather).

Its debut album was praised by such media centers as Pitchfork and Stereogum, and was named #2 Portland Album of 2007 by the Portland Mercury, which said AU “manages to erase the high art/low art boundary between American contemporary classical music and American pop music, blending them into a simple, compelling, verse-chorus celebration... (and) is the rare band that can reinvent its songs live and still manage to match their recorded quality."

David Bowie ( /ˈboʊ.i/ BOH-ee; born David Robert Jones on 8 January 1947) is an English musician, actor, record producer and arranger. A major figure for over four decades in the world of popular music, Bowie is widely regarded as an innovator, particularly for his work in the 1970s. He is known for his distinctive voice and the intellectual depth and eclecticism of his work.

Bowie first caught the eye and ear of the public in July 1969, when his song "Space Oddity" reached the top five of the UK Singles Chart. After a three-year period of experimentation he re-emerged in 1972 during the glam rock era with the flamboyant, androgynous alter ego Ziggy Stardust, spearheaded by the hit single "Starman" and the album The Rise and Fall of Ziggy Stardust and the Spiders from Mars. Bowie's impact at that time, as described by biographer David Buckley, "challenged the core belief of the rock music of its day" and "created perhaps the biggest cult in popular culture." The relatively short-lived Ziggy persona proved merely one facet of a career marked by continual reinvention, musical innovation and striking visual presentation.
