LENOX, Mass. — James Levine opened the Boston Symphony Orchestra’s summer season at Tanglewood here exactly as he closed its formal season at Symphony Hall in Boston, with a concert performance of Berlioz’s biggest, meatiest and most hair-raisingly passionate score, the opera “Les Troyens.” As a concession to its five-hour duration, he adopted a time-honored way of presenting it, with Part 1 (the first two acts, “La Prise de Troie”) on Saturday evening, and Part 2 (the final three acts, “Les Troyens à Carthage”) on Sunday afternoon.
