It’s been over nine years since I last listed my favorites. But, in my entire life, it wasn’t until about a year ago that I came to greatly appreciate two composers whose music I had never really cared for---Mozart and Haydn. It all started when I was hit as if by a bolt of lightening out of the blue by Mozart’s "Hoffmeister" String Quartet (#20). Hard for me to believe how for so long I just could not stand this composer. From the "Hoffmeister", I skipped to other Mozart chamber works...and then I started listening to Haydn’s Piano Trios, etc. Astounded again. Based on their chamber music alone, these two composers now sit atop my favorites list along with Brahms, Dvorak, Debussy, Ravel, Tchaikovsky, Borodin and Schubert.

Did you discover a love for bluegrass at the same time? :) 

Not being completely facetious, I usually hate bluegrass and Mozart for the same reasons.

Best,
