Return to Forever sample

So I'm listening to this Return to Forever album right now - Romantic Warrior
There's definitely something here at 0:50 seconds, and it's bugging me out coz i've heard this chopped on something, maybe from Insight or Mr. Lif.

Anyone know who bit this?

Nah?

no idea, sounds cool though.

edit***
actually, sounds like it could be the first track on cannibal ox the cold vein, called iron galaxy. dont know for sure though, it def sounds similar to the sample from 3:21 to 3:26
