Hello, I played Biber's Passacaglia Wed. and am very impressed with this composer. I cannot believe it has taken so many years to discover this great solo piece. Good piece for a wedding. It is very moving. Now I am considering buying the 12 sonatas to work on, which should be a pleasure. If anyone can give me a review of the sonatas I would appreciate it. I also need a good link for a detailed biographical sketch of Heinrich Biber. Thanks.
