I love violin music, from classical to popular, even the fiddle. The violin is my favourite instrument, to me it is the most expressive.
I recommend these sites (Chloë Hanslip who is so refreshing and Tasmin Little whose recording of Bach's gavotte you can download to your MP3 for free) :

I just bought the CD of Daniel Hope playing Mendelssohn's violin concerto : http://www.danielhope.com/
I also have all the Bond CDs. Their music is happy and you cannot sit still but have to jump up and dance. http://www.bondmusic.net/
