Oh my goodness, the change-up at 0:55 on this song is beyond incredible.
Kayex are a Perth-based duo and this is their debut track. It's a hell of an introduction, might I add -- and proof that the Aussie market hasn't gone stale (contrary to my perception as of late).
I don't have a whole lot more for you on these guys; they don't appear to have much of a social presence just yet. For now, you'll have to just sit back and enjoy it.
