CLASSICAL MUSIC / Upbeat: Over there

THE de-Americanisation of conductors' podia in Britain is gathering pace. Already we have John Mauceri off from Scottish Opera, and then Andrew Litton leaving Bournemouth to follow Eduardo Mata at the Dallas Symphony Orchestra. Now comes the other side of Michael Tilson Thomas's role-swap at the London Symphony Orchestra: he is going to be music director of the San Francisco Symphony from September 1995, succeeding Herbert Blomstedt, who will become San Francisco's music director laureate. There's still traffic the other way, just about, though Kent Nagano's arrival at the Halle is the sequel to a stop-over in France.
