A dizzying array of new fusion-heavy sounds will be showcased at the sixth annual Bogotá Music Market (BOmm), which kicks off Tuesday (Sept. 13) in Bogotá, Colombia, and runs through the 16th. The annual marketplace/conference/music festival, put together by the city's Chamber of Commerce, has been growing steadily, with more than 1000 local acts registering to attend and vying for a coveted showcase spot. This year, 26 acts will perform live during the week. Here are five to watch. 1. Aerophon Crew: Frank Takuma and Jefrey "Ruzto" Martinez rap hard over piano riffs, trombones and sax. But what we like most is what they rap about: hope, dreams, ambition, tempered by love of family without gratuitous or corny messaging. Aerophon's reality (the name is a blend of aerosol - they sing to graffiti - and microphone) has struck a chord. Break-out hit "Mi familia" (My family) has over 2.7 million views on YouTube. 2. Systema Solar: These guys may be indie but they're no rookies and it shows. This decade-old troupe from Colombia's Atlantic coast is a kind of tropical/folk collective that mixes dance beats with traditional rhythms (think a less electronic Bomba Estereo). Check out their latest single, "Rumbera" (Party Girl), which celebrates the spirit fo women of all stripes and colors, to an irresistible beat. 3. Burning Caravan: This sextet's music is weird and funky, a mixture of art rock and Cuban trova (in the lyrics and vocals) and klezmer music with its use of clarinet and accordion. It's a mish-mash but you'll stop and listen. "Las historias de los hombres" attempts to bring all this together in a single track. Ambitious, but it works. 4. Los Rolling Ruanas: This quartet of guys from the surroundings of Bogota is both self-deprecatingly funny and engaging. Clad in their "ruanas" (think a Colombian poncho), they vacilate between folk and 50s rock with more than a touch of good humor. Geeky but endearing, these Rolling Ruanas will get you dancing. 5. Sango Groove: This brass and percussion group from Cali mixes funk, jazz and Pacific Coast rhythms in a complex, well-executed sophisticated mix that can be both danced and listened to.
