A 1994 tape by Ghanaian musician Ata Kak called Obaa Sima, reissued by Awesome Tapes From Africa.

This release is the culmination of a 13-year story for Awesome Tapes From Africa founder Brian Shimkovitz, who bought a cassette copy of Obaa Sima from a roadside stall in Cape Coast, Ghana, in 2002. The tape was the subject of the first post on his Awesome Tapes From Africa blog in 2006—the blog spawned a full record label in 2011.

Shimkovitz began searching for Ata Kak and says "Google and endless phone calls provided no leads." It was eventually discovered the musician, real name Yaw Atta-Owusu, had recorded Obaa Sima in Toronto before moving back to Ghana in 2006.

The restoration of the tape proved challenging. Only about 50 copies of the original tape were produced, and Atta-Owusu's master DAT had disintegrated, so the second-hand copy purchased by Shimkovitz was used as the source for the reissue. The seven tracks on Obaa Sima touch on rap, techno, pop and highlife.
