BS 2000 are Adam Horovitz and Amery Smith.
BS2000 was a side-project of Beastie Boys member Adam "Adrock" Horovitz and Amery "Awol" Smith (who toured with Beastie Boys as their drummer in mid 90s). The project started as sort of east-meets-west long distance beat-trading coalition between New York based Adam Horovitz and Los Angeles resident Amery Smith. The result of that was a release of a self-titled limited edition vinyl on Grand Royal (now defunct Beastie Boys record label) in 1997. The album's 23 tracks, all extremely short and drenched in drum-machine beats and a frenzy of cryptic samples, made a splash within the breakbeat DJ world. It garnered praise from such turntable luminaries as Dan the Automator and Alec Empire. Due in part to the Beastie Boys active schedule of recording and touring, it would be nearly five years before BS2000 reemerged with a follow-up album. In 2000 the duo released a record titled "Simply Mortified". "Simply Mortified" differs largely from their first release. While it still has a drum machine at its core, the album relies less on sampling and more on keyboards and distorted vocals, both of which were absent on the first record. This time BS 2000 went on tour to support their release. During live shows they were joined by Jazz Thompson on keyboard and Alfredo Ortiz on drums. Alfredo Ortiz has toured with the Beastie Boys as a drummer and percussionist, during Hello Nasty, To The 5 Boroughs and The Mix-Up tours. Jazz Thompson was a guitar tech who toured with the Beastie Boys in the 90s.
Jazz and AWOL are referenced in Beastie Boys song Intergalactic ("Jazz and AWOL that's our team")
