I have seen Oscar and Joe Pass live but separate concerts. It was late in Oscar’s life but he still had it. It was incredible to hear his command of intricate fast right hand improv while the left hand is doing octaves and swinging.
I once went to an Oscar Peterson/Joe Pass concert at Boston Symphony Hall. Unfortunately, Oscar got snowed in in Canada and couldn’t make the performance.
Fortunatly though, they gave everybody back their money and Joe Pass came out and gave a free one hour solo concert.
I was a student at the Berklee College of Music then, and when the word got out that Joe Pass was giving a free concert, that hall filled up in no time. What a fabulously memorable night that was!!
