The other last bits from Sd are further up the thread, but man's been scarce. He killed his Twitter account and told some people he was done with music. The last releases (Sanpaku Island, Dreadful John too I think) were put up on YT and might not even be him... he had a track called Kicker or something but pulled it down.
Hopefully this is just a normal yung man freakout ting and not, say, Tri Angle fucking him over or something. He's also had some personal struggles over the last 4 years or so.
(on the off chance he's reading this: hold tight man. You're highly valued.)
