I had a chance to meet with Fabian at his home in Barranquilla. This Analog Africa article talks about Pico sound-systems, rare record battles, and secret African songs that nobody is supposed to know about.
He just shipped me one of my favorite Wganda Kenya songs of all time, the impossibly pricey and rare Tifit Hayed and some other killer latin funk 7"s.
Fabian's Africolombia blog is the most comprehensive Pico resource online. He also sells records, and gets incredible artwork made custom. Trustworthy connection, I'd know, I opened a PayPal for him.
