Have amplifier, will travel. Cuban singer-songwriter Poveda never misses an opportunity to perform, whether at scheduled shows in the funky dives of Little Havana or on a street corner near you. Not averse to playing with a band (as the rambling roster of his sometime ensemble Los Bloomers de Havana attests), he is in his element alone, accompanying his gravel-and-nicotine voice with an acoustic guitar, the click of his tongue, and the wind instrument that is his sighs.
