Well, like I said, I'd never heard Lou play before and he was up first. Let's see, I remember OUR LOVE IS HERE TO STAY, a blues (that hinted at OP's SWINGING TILL THE GIRLS COME HOME) EVERYTHING HAPPENED TO ME and something else that escapes me right now. Sean played an original called THE MONEY CHANGERS, a ballad medley of an original (GRAHAM EUEN?) and CHELSEA BRIDGE (arco for the melody on both) a blues and a solo piece called ISMIR. And Neal played I REMEMBER YOU, an original blues called BLUES FOR OKURA, SMOKE GETS IN YOUR EYES and now the last tune escapes me.
It was interesting to hear how none of these guys has a real "bassistic" approach, pretty much ANY of them, the solo line could have been a tenor or trumpet or guitar etc. Solid, solid walking lines but immediately responsive to any voicings or new directions Mike Kanan (the pianist/accompanist for the workshop) would suggest. But given this "similarity" in concept (if you will) these guys all sound so different. Lou has a lot a chromaticism in his playing, Sean has probably the most "modern" approach, Neal is one of my favorite players and wonderfully melodic. Well ALL these guys are wonderfully melodic.
During the Q & A we found out that all 3 guys play piano (Lou also plays guitar), but they all approach first learning a tune by learning and internalizing the melody - get a range of sources (books, recordings etc.) to get the original composer's approach (including the harmony) and THEN start seeing if you're hearing a different approach, different harmony. All three of these folks were part of the program (Lou earlier but Sean and Neal at the same time) at Manhattan School of Music; Lou studied with David Walter and Neal and Sean with Orin O'Brien. Neal had been studying privately with legit teachers since he was a teenager. Lou stopped at Manhattan after a year (he went out on tour) but was studying with Lennie Tristano after that. Everyone still practices arco, but Sean is the only one that is actively pursuing the arco voice. Neal particularly said that the great thing about learning a legit approach is building a solid left hand. When asked what was it about bass that they each loved, the sound was the answer. Sean said he couldn't be specific, he loved the sound of so many instruments, but that he "knew" that bass was "his instrument".
Then they played (all together, trading the melody and soloing in 8 bar sections) THESE FOOLISH THINGS accompanied by Mike and then BLUE MONK without accompaniment.
Any specific questions to jog my poor memory? Maybe Fred will chime in as well.
