Greetings,
I certainly hope that this missive isn't considered spam. There is an
interesting recording available presently of Bartok on the Arbiter
Records label (Arbiter 143 - Bartok in the Desert) - possibly it has
already been discussed here.
A streaming audio interview with Allan Evans, concerning his discovery
of Marik (who only made two LPs, and quit concertizing after WWII), is
at http://www.studio360.org/show061805.html
I find her playing has a generous freedom of motion, and to be rather
insightful for its tempos and accents (including rhythmic accents).
