Why don't we make a list about the piano concertos which have all movements together?
One question. What is the purpose of this list? A piano concerto can't be judged on the number of it's movements, or whether or not they're played attacca.
Erm.... there is a clear break between Movements 1 & 2... so I wasn't sure if that could be considered.
Rachmaninoff's 3rd Piano Concerto.
The movements aren't together in that work.
