Southern Light - Worth a listen

My music tastes are rather catholic so take your pic. However, one should not get stuck in a rut so expand your mind baby, expand. All artist listed are worth a listen...

Blues:
Lightning Hopkins (if you really want to go back to the roots of blues)
Keb Mo (more recent and well recorded)

Jazz:
Diana Krall (hi fi evaluating stuff, sensual, better than any porn movie)
Jacques Loussier (espescially his renditions of Bach)

Rock/Progressive:
This genre is huge but here are some of the better artists
Pink Floyd (a must if you are serious, Wish You Were Here and Animals)
Led Zepelin (although I have always considered them to be a blues band)
Nine Inch Nails (if you are brave enough)
Patti Smith (the original rebel)
P J Harvey (the one and only)

Goth/Metal:
Type O Negative (dificult to classify, a pity that they are American)
Diary of Dreams (Stimmulation is still my favourite)
Rammstein (addictive stuff, be warned)

Celtic
Loreena McKennit (a definite must)
AfroCelt (dificult to categorise so here they are)

Classics
Mahler (who else, give the second symphony a hearing):
