The word mixtape has plenty of different interpretations. It used to be that mixtapes were actually DJ sets recorded on cassette tapes, but with the coming of the digital music age, the name remained the same, but the definition expanded. Nowadays, people call mixtapes many different things, some of which are not necessarily mixed and most of which were never taped. Here we try to cover them all. In this column, Juan Data gives you a worthy one every week.

DJ: Doctor Stereo
MIXTAPE: Exitos En Castellano

Usually when we go back in time on this column, the furthest back we get is the ’70s, maybe the ’60s, sometimes. This week, however, a Doc Brown impersonator invited us on a Delorean ride and set the timer to the ’50s, to the era of mambo and bolero, and from there he took us all over Latin America, searching for some soulful roots in the form of mono LPs.

Doctor Stereo is an Argentine vinyl archeologist, DJ, and producer whose original music and remixes have been released by several prestigious labels including New York’s Names You Can Trust, Germany’s Resense and Sweden’s G.A.M.M. Here we have him doing an impeccable 25-minute mix of pure vinyl that, if you close your eyes, will make you feel like you’re dancing at your grandma’s senior prom. Just don’t make out with her, it’s weird.
