NB, Although I'm very much a classical pianist, I've recently been playing a number of arrangements by Mercuzio. Although he works with popular tunes, his arrangements feature plenty of classical techniques. This often results in extremely dense textures with numerous different voices at once. Also included are a Keith Jarrett transcription and Rick Wakeman's arrangement of "Life on Mars".
Here are "Summer of 42" and "I will wait for you" by Michel Legrand, arranged by Mercuzio
