They don't come much bigger than this; John Dahlback, Avicii and the vocal talents of Andy P all combining forces to deliver a truly mammoth release on JD's own imprint Mutants. Avicii is known for his massive main room sound delivering recent cuts 'My Feelings For You' and 'I Feel Love' to critical acclaim, and John Dahlback has had similar success with 'Blink', 'Everywhere' and 'Bingo', so for 'Don't Hold back' you would expect nothing less than huge and boy do they deliver.
