Brisbane producer Callan Alexander (aka cln) is back with new music.

He has released his woozy new single "What I Know," which features vocals from ex-Porsches member Carl Fox. It comes as a preview of cln's upcoming debut album.

"This song has been in the works for a few years now. Carl and I started it at a writing camp in Sydney. I think it was probably late 2016," recalls cln of the new song. "He went away into the booth and had the first verse done in about 10 minutes."

While Fox's vocals might have been a relatively easy fit, cln says it's taken him a while to get the instrumental side of the song right. But now that he has, the song has been releasd.
