This was a thrift shop find (99¢), in okay shape (it's pretty crackly). I had recently read a New Yorker essay about Gesualdo when I saw this LP, and it inspired me to pick it up. It is not on CD.
As far as I can tell, this LP contains just one instrumental work by Gesualdo. The rest of the pieces are by Nenna. Both were known for the unusual chromaticism of their work.
Carlo Gesualdo: Gagliarda a 4
Pomponio Nenna: Ricercare a 2
Madrigals, by request:
Pomponio Nenna: S'io taccio (Book I)
Pomponio Nenna: Ecco, O mia dolce pena (Book IV)
Pomponio Nenna: L'amoroso veleno (Book VII)
There's a lovely version of Gesualdo's Gagliarda on youtube: http://youtu.be/txBWSnmSs8w
