Classical Classroom #1: Vivaldi's Autumn

I recently discovered a PostCast called Classical Classroom, where the host Decia Clay talks with “advisors” on learning different great pieces of classical music. The tone of the postcast is very approachable (not sure how I can better describe it) to classical music newbies like me. In the very first episode, it introduces the Vivald’s Four Seasons Concerto, "Autumn" by two distinct violinist: Itzak Perlman violin solo, Londo Philharmonic I.
