In the discography in the Wikipedia entry for Perahia there is nothing later than Brahms excluding that one Bartok recording (presumably done at Solti's suggestion). On Youtube, however, there is a selection from Rach's Op 39 (perhaps the influence of Horowitz?).
Article from 2008 on catalyst for Perahia's Bach recordings :
He also did an album of Bartok solo piano works. Really good.
And he recorded a work by Michael Tippett.
