probably not premieres?- anyhow, a new recording on the way from Grand Piano (the 24 preludes Op.102, a Berceuse Op.83, 3 movements- all?- of a suite no.4, Op.39, and one movement from his Suite no.2, performed by Cristina Ortiz.) - www.naxos.com/catalogue/item.asp?item_code=GP637 (http://www.naxos.com/catalogue/item.asp?item_code=GP637). (Hrm. Stephen Hough recorded 13 of the Preludes for Hyperion in 1996, and the Berceuse also. Joop Celis recorded all the preludes for Chandos, also the Suite No.4 (Mignonne) (and the 3rd suite but not the 2nd nor the Berceuse? - lots of other stuff, though, I see.)
As of today, this is available for download at eclassical.com.
