Dr. Dre has suggested that his long-awaited, dead, then not dead, then dead again album "Detox" might actually be released after all ... and it all went down at a Golden State Warriors practice.

Dre and Jimmy Iovine were watching Steph Curry and Kevin Durant at a Warriors workout on Tuesday when ESPN's Chris Haynes brilliantly asked him if Detox was permanently shelved.

Dre's response -- "I'm working on a couple songs right now. We'll see."

BOOM!!!

Dre has been working on Detox since 2002 -- but seemingly closed the door on the idea in the HBO series, "The Defiant Ones" ... saying he's moved on.

"I never had any connection with [Detox], it didn't work."

He added, "I'm never gonna do that again."

Never say never ...
