Over the past month I downloaded three new mixtapes, given away by the artists or DJs who created them. One from Sri Lankan rapper/producer M.I.A. (ViCKi LEEKX) and another from Kid Sister, a Chicago-based rapper (KissKissKiss). The third, a ‘proper’ mixtape full of various artists, Who’s Ya Best Emcee? from Femcees is on heavy rotation in my apartment and on my iPod. These mixtapes are not ones that you and I remember. They are not the cassette tape kind, where you spliced together your favorite songs for either a party mix or to give to that special someone. (If you don’t know what a cassette tape is, you’re probably too young to be reading this blog). No. These mixtapes, likely the ones your teenagers are listening to, are a significant part of the hip-hop industry and a critical part of promotion. But they do originate with those cassette tapes from back in the day.
