The concerto concertante for two pianos and orchestra and viola concerto were recorded on LP; the university library here has both recordings (the former was coupled with the only previous recording of the first symphony known to me), and I was particularly impressed by the viola concerto, which has, I believe, been recorded only once but released several times in several different (LP) couplings. The string quartets, some of which (#3 on Koch, #7 on Parnassus, others?) have reached CD and most of which reached LP in some form or other (I think #5 may have been an exception,) are rather good as well (I thought #3 particularly so the first time I heard it.) There's also two (?) violin sonatas, of which the second received a few outings on record including at least one on CD and the first was premiered on Koch a few years back (Gearhart/Owings, from 1997- library here has it too, but I haven't heard it yet. I see from their listing that the CD contains a third violin sonata as well, unnumbered and brief, as well as other works.) Eric Schissel
