Now you've done it !
Power of Soul is a very good album - worth checking out. If you like stuff in a similar vein albeit with a huge dose of funk added then check out Headhunters & Fat Albert Rotunda both by Herbie Hancock, Headhunters especially is truly amazing.
Attica Blues by Archie Shepp is more along the lines of Loran's Dance but with a twist (Archie Shepp was one of the main men in the avant garde jazz scene) don't be put off tho' it has an all time classic track on it, Blues For Brother George Jackson.
For more contemporary stuff check out the Future Sound Of Jazz compilations from Compost Records, absoutely brilliant. One of the best artist albums on Compost Records is Exercise De Styles by Les Gammas - another cracker.
A British band worth checking out is Two Banks Of Four lead by Rob Gallagher ex-Galliano superb albums and an excellent remix album of their stuff by other artists.
Old school stuff try The Stylistics self titled first album which been remastered contains People Make The World Go Round, one of my all time favourties.
Some other essential artists I would recommend are Gil Scott Heron, David Axelrod, Curtis Mayfield, Terry Callier, Jon Lucien, Betty Davis (one of Miles Davis' exes), Jimmy Smith (check out The Cat used for the Panorama theme music !).
I'm probably being presumptious with these - it's just my enthusiasm for the music
I need to stop now as I could be here all night. Enjoy (hopefully).
