Concertos 1 & 2 are played by many virtuosos today and are widely available. However concertos nos. 3-6 are rarely played and are available nearly nowhere -- not in book stores or internet. They are only available through a special order. I find it strange. Those concertos are awesome and so difficult. I really like concerto no.3 and would love to start playing it but I can't find the scores anywhere. If anyone knows any other ways of getting these concertos that would be greatly appreciated. Thanks.
