Walden this, Walden that. The Aussie teen has made quite the buzz since landing on our artists to watch list. Dropping his second original production, “Intropial,” and a remix of The Only’s “Looking Back,” the rookie has satisfied studio efforts in the month of January — but he won’t stop there. Walden takes his turn on Anakyn’s “Point Blank” — which has previously been revisited by Nicky Romero — for another vocally sophisticated big room effort. Walden has solidified his signature sound, a mastered product of chords and strings that evokes a pristine sense of audio euphoria.
