Classical music wise I like the carefully constructed inventions of Bach and Clementi.
I like the atmospheric works of Debussy and the even more atmospheric works of Ligeti. I like the gentle flowings of Satie, the determined eccentric.
I like pieces by Ravel like "Ma mère l'Oye". I like the aggressive percussiveness of Bartok.
My mother liked Mozart and Beethoven, to be different I avoid the composers she liked.
