One of todays greats and the younger generation have made him a house hold name with his work on the Battlestar Galactica series.

Gets my vote – the orchestral music is wonderful and the character themes work as well. Mention to anybody that he uses Japanese Drums and bagpipes in the same piece of music they look a bit puzzled though !
