If you’re in the mood for a good smile, check out Red Bull Music Academy’s recent documentary “Ata Kak — Time Bomb” — an inspiring yet randomly fascinating documentary following music blogger Steven Shimkovitz on his search to find the elusive 1990s Ghanaian lo-fi dance and hip-hop musician Ata Kak. After discovering the musician’s first cassette album “Obaa Sima” (released in 1994) while studying music in Ghana in the early 2000s, the blogger wrote about the cassette and went on a near-decade-long search to find the musician. Meanwhile, Ata Kak’s music — a wild, bizarre and funky combination of 1990s house, electronic, hip hop and high life — trended in music clubs around the world. This 25-minute documentary, which can be watched over YouTube, is about finding Ata Kak, who still lives in a small village in Ghana, and telling him that the world adores his music. What unfolds is a tribute to homegrown music and art of the 1990s and a heartwarming story of love, life, laughter, and, of course, hope.
