It's easier to make a list of the unavailable than of the available. Not: Muti, Abbado, Gilbert, Levine, Nezhet-Seguin, Dudamel, Salonen (sob), Jurowski, C. Davis, A. Davis, Haitink, Mackerras (double sob), Barenboim, Nelsons, Rattle, Runnicles (sobbing even more)
People we don't want: FW-M (busy with contracts in Vienna and Cleveland, anyway), Mehta, Previn, Schwarz, Ashkenazy, Maazel, Masur. :)
Been there/done that/don't come back except as a guest: Ozawa, de Waart, Blomstedt.
Probably not: Simone Young
Wish We Could: Le formidable Boulez (say it with a French accent), nearly 85 and with regular guest gigs in Chicago and Cleveland
I would look to the frozen north, and I don't mean Canada). One of the Baltic states, Scandinavia, Finland. There's someone there, maybe someone we know: Osmo Vanska? Sakari Oramu? Where are Neeme Jarvi and Mariss Janssons working? How about Marek Janowski? Eschenbach? Dohnanyi? But the latter two are both 70-ish. So is Frubeck de Burgos.
Favorite from the frozen north: Susanna Malkki, who is Finnish, female, young, and made a big splash in NY at Mostly Mozart a year or two ago.
Who has had a great rapport with the orchestra the last few years? Could Conlon wedge in an orchestra? Yan Pascal Tortelier?
Who is currently conducting at Birmingham, Liverpool, and Bournemouth in Great Britain?
What about Marin? What about Robertson?
Where does Dutoit fall? Spano?
Former assistant conductors of East Coast orchestras: Julian Kuerti, Shi-Yeon Sung, [NYPO had a good assistant as well, a young woman from China, but I cannot dig up her name]
Current, well-reviewed, incredibly young assistant conductor of LAPO: Lionel Bringuier
What about former assistant conductors of SFS? Alasdaire Neal, James Gaffigan (who is VERY good), Edwin Outwater?
Or maybe somebody we don't know yet. Who woulda thunk Alan Gilbert would get the NYPO job AND make a great success of it?
