Sunday at 1 p.m. on WRTI-FM (90.1), the Philadelphia Orchestra, led by guest conductor and early-music specialist Richard Egarr, presents a program from November highlighted by Vivaldi's Four Seasons violin concerti, with violinist Giuliano Carmignola. The Vivaldi is followed by a suite of 17th-century English composer Henry Purcell's music for The Fairy Queen, and Haydn's Symphony No. 101, one of his great "London" symphonies, nicknamed "The Clock" for the ticking rhythm of its second movement.
