Who's the best blues harp player.

Alot of really good ones have already been mentioned but Mark Wenner of the Nighthawks should be on the list as well. He's got one of those killer gravelly voices to boot.

Although I am a huge Junior Wells fan (Junior was a superb vocalist as well), I'd have to give the nod overall/all around to Little Walter with respect to playing. Sugar Blue is also a superb modern day player; technically there are not many who can hold a candle to him but I think he finds it difficult to fit his ego into most rooms.

honorable mention-corky seigel,paul jones(ex manfred mann),the late great paul butterfield,the late great keith relf.

-Walter Horton (on the album: "Johnny Winter"),
-Whomever played on "Must Have Done Somebody Wrong" Allmans/Filmore East
-Whomever plays for the 'Stones (Jagger?) particularly "Midnight Rambler"
-Whomever plays for Zepplin (Zep-II, "Bring it on Home")

Sorry I'm such an ignorant music lover...

I am surprised nobody mentioned Howard Levy, the brilliant harmonica/keyboardist who used to play for Bela Fleck's Flecktones. He is the only harmonica player I know that can play sharps and flats on a diatonic harmonica. And who can play harmonica AND piano at the SAME time. And a very good composer in his own right. After Flecktones, he also was a part of the group Trio Globo. I also found him as a session player on many other recordings of famous bands. A very talented and unique musician.
