| Robin,
well I find mark's harmonic language to be similar to Kurt's, so some of the things I've taken from recordings that they are both on are how well they play together, their phrasing, and their very recognizable sound, and note selection. Mark has incredible control in the upper register of his instrument, and such a connection with the sound of his horn. It's something quite moving when you play with him. It's a different level of communication when you make music with someone who has that much respect for the horn, and for the music.
i'm not sure I have three questions for billy hart, but the main focus of what I would ask him if I had the chance would about time.
He's played with some of the most swinging artists in history from Wes Montgomory, Jimmy Smith, Stan Getz, McCoy Tyner, gerry mulligan. I would ask him about touring with those artists, conversations with those artists, what he got from them, and how his process was effected by those people around him in such an era as the 60's. He was also a member of bands of three of my favorite artists. Tom Harrel, Joe Lovano, and Charles Lloyd. So I would have questions about working with those artists, and what kind of effect those profound artists have on billy's life and playing.
Eddie......
not sure I've taken too much personally from his playing, but it's something that is in my ear as he has been a member of some amazing groups that I've checked out for years. I dig some of his stuff with Bill Evans, and of course chick corea's "three quartets" album. The playing on this album is increible from everyone in the band. I've transcribed all the piano and sax solos from this record.
Hope that was somewhat of an answer you can use.
Easy,
Janek |
