I like the blues but only listened to it on internet radio. can you recommend some artists?

Bobby Bland (inspiration for both Van Morrison and Rod Stewart)
Bettye Lavette (she's got some oompf, bit stereotypical)
Howlin' Wilf
James Hunter (current, english, sounds classic american, Toe Rag studio's produced...not well known but superb)

...to name a few. Enjoy!
