I noticed a certain Weather Report sample (Young and Fine) 10 years ago in this song and somehow forgot about it until now. Perhaps this was the first sample of Jaco used in a hip hop tune? Anyways I thought it was pretty cool. The growling bass is unmistakable.

Listening To: A Tribe Called Quest - Butter

Haven't heard that before? But you're right it's unmistakable. Amazing, only a short sample and still it puts the on your face right away!

Listening To: Allyn Robinson backing up on "Mambo Man" Hot!!

I too hadn't heard this before, I believe you're right, possibly the first Jaco sampling, sweet, thanks!
