Re: Great tune by Stan Getz Quartet (ft. T.Williams) - what is it!?
The tune is Times Lie by Chick Corea. There's a nice version of it on the album Moon Germs by Joe Farrell with Jack DeJonette, Herbie Hancock and Stanley Clark.
Thanks for linking to the video. I'm obviously a big Tony Williams fan, especially his pre-black dot stuff.
