I have the following Arte Nova Disks in my collection, in more or less
chronological order:

74321 27801 2 Schubert - Symph.3; Rosamunde; Concert Piece. SWF SO/Gielen
74321 27799 2 Schoenberg - Choral Works. Suedfunk Chor/Huber
74321 27793 2 Mossolov - Piano Works. Lombardi
74321 27773 2 Carter - Orchestral Music. SWF SO/Gielen, Oppens/piano

These range from pleasant (Schubert) to pretty darn good (Schoenberg).  But
hey, at $5-$7 per disc, you really can't go wrong.  My general impression
is that the quality of performers and recording at least rivals that of
Naxos, and Arte Nova seems to produce more modern work.  So be adventurous
and explore!
