Waldo Fernandez is a man of many missions. Nearly all of them have to do with rescuing Cuban music, television, and film from the ravages of censorship and decay. In his office he proudly displays an original still from the 1949 movie Sandra, The Woman of Fire, starring Rosa Carmen, but he needs more than a sheet of glass to save the film stock itself. Fernandez buys 16mm footage of the movies, musicians, and variety shows of his homeland wherever he can, transfers the material to video, repairs damaged images frame by frame, then lovingly edits together music videos and full-length documentaries (such as this year's History of the [Cuban Television Network] CMQ, complete with commercials from the Fifties). Beginning this spring, his work can be seen on the program Longing for My Cuba on WLRN, Sundays at 10:00 p.m. If you like what you see and hear there, stop by Marakka 2000 on the east side of the Palmetto and pick up a copy of the video or a related CD. Or request a rare title by your favorite obscure artist. Fernandez's motto: If it exists, I can find it.
