In the late 1990s, hiphop entered the underground through three labels. One was New York’s Rawkus Records. Another was LA’s Stones Throw Records. Third was the Bay Area’s Quannum Projects. The third label housed three important groups, one of which, Latyrx, consisted (and still consists) of two rappers: Lateef the Truthspeaker and Lyrics Born. In 2006, Latyrx dropped one of the most original albums in the history of underground hiphop, The Album (it included production work by DJ Shadow), and in the ’00s, both rappers released a number of remarkable solo albums and singles. This show will certainly provide entertainment (Lateef and Lyrics are very active on the stage), great music, and a satisfying history lesson.
