****Can a solo performer compete at creating musical emotion and expression cpmpared to a group?****
Of course it can. Apples and oranges. Is Horowits playing a Beethoven piano sonata less capable of musical and expression than the Berlin Phil playing "Eroica"? Is it lesser music? Of course not. The symphony may be on a grander scale, but is the sonata lesser music? In fact, the solo artist in jazz or classical faces a bigger challenge; that is one of the things that makes Mehldau's performance so amazing.
