I edit a web site called LAAMB - short for Lincolnshire Arts and Music Bulletin. It's all about promotion for Musicians and Artists, not just in my local area, but all over the world. If you google Lincolnshire Arts, you should get the link.
As far as music is concerned, it's mainly for indie based artists, but does have content for more mainstream musicians such as Robert Wyatt (Soft Machine/Matching Mole), Tony O'Malley (Kokomo), Dave Hunt, Talinka and Hataken. There are Profile pages including links for musicians, artists, writers, actors, venues, businesses, anything to do with The Arts, so do have a good look around.
I especially suggest a vist to the Charts
and Musician pages.
Do get in touch with any questions.
