I didn't see a reference to Mozart's Sinfonia Concertante in the responses to this question. Not, I suppose, technically a violin concerto, I can't imagine anyone interested in the concerto literature not being drawn to this wonderful work in which the violin shares the stage with the viola. It's a more mature work than Mozart's violin concertos proper, with a wonderful orchestral sound; as with other top-drawer Mozart concertos, the slow movement is heart-breakingly beautiful.
