My first Prokofiev group posting - let's hope it's not my only one!

Multiple sources confirm that Britten admired Prokofiev's music and if you
listen to his earlier works, especially his underrated Piano Concerto, op.
13, you would be hard-pressed to deny Britten's debt. Does anyone know of
specific sources (biographies, journal articles, etc.) which deal with this
in more than a sentence. I'd also be interested in similar sources regarding
Prokofiev's rivalry (to the extent that it was one) with Stravinsky.
Something to the tune of Chout - Petrushka, Scythian Suite - Rite of Spring.
If nothing's out there, I'll try to write something myself, but there's no
use revisiting what has been well covered already.

Thanks in advance,
Ben Malkevitch
