Can anyone give a link to a sheet music website that has prokofiev's 1st piano concerto in d flat major.
The piano score!
I think you will find it is copyright protected - he died in 1953 - in the US the copyright will expire 75 years after his death and in Canada 50 years, assuming his home country (the Soviet Union as it then was) has copyright treaties with the US and Canada. Recommend you just buy the score if you can find it.
