Re: Looking for a Rocking Blues Band with Blues Violin/ Viola/ Fiddle

The Black Diamond Express as Mike mentions are a good example. Their album has got great reviews in Blues Matters, Classic Rock Bluea and Rock N Reel in the last month.
They do play a lot of rocking blues, but also some folk and celtic styles. Never Was A Lass on Jock's Juke Joint also features on their album which was recorded live:

Another favourite of mine were The Fortunate Sons. While the guys are still active, they have changed their style and name since this song:
