I just heard the news that blues harmonica player Paul deLay passed away back in March. He was only 55, so like William Clark a few years ago another still young harp player taken from us far too soon. R.I.P. Paul.
If you don't know deLay's music, and you like the blues, you should really give him a listen. His personal life was such that he had paid some dues, but there's a lot of joy in his brand of the blues. He was a tremendous blues harp player - probably one of the two or three best of his generation. He was also a good singer and fronted his band well.
You might want to start with deLay's Nice & Strong for an introduction to his music.
Another good option is his Ocean of Tears CD.
