Together, they're A plus D – as in Adrian & the Mysterious D. Known mostly as the couple who helped bring mashup culture to America, the duo have forged a reputation as crowd-pleasing selectors who not only shamelessly bridge the gap between genres, but between the alternative and the mainstream. This is best evidenced by the success of their club Bootie, the first and biggest mashup bootleg party in the United States.
