Following last night's season-opening gala with Lorin Maazel and Yo-Yo Ma — and the very popular free dress rehearsal yesterday, the free simulcast of the concert outside Avery Fisher Hall last night, and the live telecast on PBS — the New York Philharmonic begins its 2007-08 subscription season this week. Tonight and for the next two evenings, Maazel conducts a program featuring Beethoven's Violin Concerto (with the acclaimed young musician Lisa Batiashvili as soloist) and Tchaikovsky's Symphony No. 2 (the "Little Russian").
