Heifetz, Piatigorsky, Primrose, Pennario
"Franck - Quintett, Brahms Sextet" (Vinyl)

Part of a lengthy series of recordings that began as Heifetz and Piatigorsky enjoying playing chamber music in their own homes eventually led to the inclusion of other great recording artists of the early 20th century.

The Franck quintet isn't as famous as his quartet, but it's a notable work. The real fun piece (for me, anyway) to hear is the Brahms sextet which features some of the gnarlier writing for viola in romantic chamber music writing.
