In your opinion, what's the hardest rock song to play on piano?
My vote goes for Jungleland by Bruce Springsteen. Thoughts?
Sweet Home Alabama (Lynyrd Skynyrd) and Ramblin Man (Allman Brothers Band) have some great piano work so definitely check those out.
If you include organ, then take a look at the solo from Highway Star by Deep Purple, Jon Lord is a monster, plus look at stuff from Rick Wakeman from Yes because he is phenomenal.
