Mikkel, I can heartily recommend this recording, which has four of her works, including three of the psalms. John Eliot Gardiner, the Monteverdi Choir and the LSO do a sensational job, and the Stravinsky performance is also outstanding.
This is the one, I already have.
I second this recommendation. Excellent performances throughout.
I can also recommend these recordings:
And I got this one from the library, though the cd was too damaged to play.
But so far I can see, since the Psaume 130 lasts about 30 minuttes for orchestra, chorus, organ and soloists, I thought she must have written a lot!
