Hah! I'll win the seniority title here, I'll wager--
In 1972 or 73, I think----it's all a little hazy now--my guitar player friend said to me "Hey, this album has some great bass playing on it. Check this out!"
The artist was trumpeter/fluegelhornist Chuck Mangione. The album title was, I think, simply "Live". The bassist was Tony Levin--even with the shaved head, back then!
He was absolutely scorching. The group was two horn players (one playing some electric piano), him, and, I'm pretty sure, Steve Gadd (!) on drums. Levin did a great job of filling up the sound of the group--for the time, sounding pretty revolutionary. (As a point of reference, Stanley Clarke was just starting to take electric bass seriously about that time, according to interviews I read back in the day.)
All Levin's later successes were entirely unsurprising to me, based on what I heard back then. Of course he would fit in with King Crimson and Peter Gabriel! It made perfect sense.
All Levin fans should listen to this recording.
