We all have guilty pleasures. Secret indulgences which, if others knew, they might think less of us. Â A personal trainer who has a secret cache of Hostess Twinkies. Â A haberdasher who buys his clothing at a secondhand shop. Â A chef who eats macaroni and cheese out of a box. Â You get the picture. Â The music world has it's same kind of secret pleasures. What do orchestra conductors, (and musicians in general, for that matter), listen to when they're not preparing to conduct? I have been asked that question many times. Â There is also the non-stated version of that same question, which goes something like this. "It must be wonderful to be able to be surrounded by classical music all day!" Â Well, it is! There are many classical works, old and new, that I really never tire of hearing and I could never imagine being without. Â A case in point is Beethoven's 5th Symphony. Â It may sound cliche, but it's absolutely true. Â I have heard a live performance of that work twice in recent years. Â Each time, I have heard it differently. Â Maybe it was the ensemble, the conductor, the hall, my mindset that day, but I heard and enjoyed the work in two entirely unique ways during those two performances. However, just as I would not be without a regular dose of Beethoven, I would also not be without regular servings of The Beatles. Â Then there's Adele, Big and Rich, Maroon 5, Sugarland, and The Black Keys. Â My listening habits change with the weather, my mood, circumstances, and sometimes just what pops up on Pandora or is suggested by a friend. ProMusica's Timothy Russell likes to say that his favorite piece is whatever he's conducting at the moment, but I'm sure he has a long list of favorites, based on his many years in the music business. The L.A. Times checked in with 10 well-known conductors such as Gustavo Dudamel, Richard Egarr, and Michael Tilson Thomas to see what's in their iPod. What are some of your favorites?
