Ghanaian-Canadian singer Kae Sun teams up with Alister Johnson aka DJ Catalist — the brains behind Zaki Ibrahim's track of 2k11 choice "Something In The Water" — for his latest single. In "We Changed" Catalist crafts an underworld bass dub laced with hip-hop beats which Kae Sun fills with soulful croons of a past-lover, now-friend.
