Try Anthony Pleeth's Vivaldi set on ASV # CD GAD 201. He uses a baroque
bow, gut strings and historically informed approach. He used to be Trevor
Pinnock's principal cello in the English Concert. Christophe Coin is also
good but Anner Bylsma seems a little eccentric and fussy in these works.
I think Pleeth tops them both.
