Mr. Hsieh, the previous reviewer, has gotten the basics right. This is splendidly eccentric and innovative music, meant to entertain you with virtuosity. John Holloway is a rare musician, one who has steadily improved his performance, from quite good to superb. The four Biber sonatas recorded here are full of contrasts and surprises, so that listening to several in a row lacks no sense of variety. If you've ever wondered, by the way, what difference gut strings on a fiddle and historically informed bow technique could possibly make, do yourself the favor of getting this CD. You'll HEAR the difference in the sound the violin makes.
