Tell you what, there's such a great amount of local talent in the UAE, it's amazing.
Just a few acts to watch out for that deserve a really go shot at it are IMHO:
Juliana Down - Rock/Indie band - from Dubai/Abu Dhabi
Killosal - R&B - 2 students from Abu Dhabi
Madman and Phat Mo - R&B/Hip-Hop - From Dubai
Desert Heat - R&B - Dubai
DJ KV - Trance - Dubai - currently mixing it up in Ibiza - yeah baby!
Jaxxma - R&B - Ronnie Jaxx and Av Deep from Madnights
Could do with some more dance type acts though, but looking good so far.
