I would like to recommend the Sonata in G Minor for Violin and Piano by Tomaso Albinoni (So 33) for your archives. It is a really nice piece and I think it would make a great addition to your library. I am not after this piece myself, but I play it on the violin and I really enjoy it, and I would like to recommend it to you.
Thank you for considering it, as I say, it is a really nice piece. If you would like to listen to it, it is available on an album called 'Six Virtuoso Violin Sonatas of the Baroque', which is available on iTunes. Anybody who likes Baroque violin music will really enjoy listening to it.
Thanks again for your consideration, and for your brilliant website!
