Purchased tickets on a whim, based pretty much solely on what I knew of the artists' music from 3 Gary Burton CD's and 1 Chick Corea CD in my music library. I figured it would be an awesome, yet typical, jazz concert with the two headliners backed by bass and drums. I found out only after buying that when this duo appears together, it may often be JUST them. I wasn't sure I liked that, but that sentiment evaporated very quickly during the first piece.
Having loved Gary Burton's music over the years, I feel the CD's I own don't do his level of talent justice! He was incredible in person! Amazing to watch.
I didn't love the 2nd half quite as much because the entire 2nd half also included the Harlem String Quartet. While I can certainly appreciate their incredible talent as well, their overall sound isn't my favorite cup of tea. Especially the 2nd half seemed much more academic in musical style - more like a hip recital than a mainly jazz-based concert. It was awesome, but I liked the first half better.
If someone asked me what kind of concert this was, it wouldn't be accurate to just say a jazz concert. While it definitely had many jazz elements, there were classical, concert, modern, afro-cuban/latin elements, etc. It was multi-faceted in style and much more structured music than the typical jazz concert that has the statement of a theme, several improv solos, then re-statement of the theme. Most of this music was well structured, written out - as you could see by the pages and pages of music.
I would go again in a heartbeat. But it's important to understand some musicians can be all over the map depending on what cycle of their musical career they are in, or who they're performing with. Others, you can pretty much know what to expect. Chick Corea and Gary Burton definitely are the former. Same with Wynton Marsalis, for instance. I've heard some of Wynton's stuff that I love and other music that is just too experimental or dissonant for me. I based my decision to drive 3 hours to this concert on some CD's of mine, none of which were the duo together as the concert would be. That was probably a mistake, though in this case the outcome was still wonderful. But just know what you're buying! Check out YouTube for some clips.
