You mention Bob Marley so deepen the Reggae love with:

BURNING SPEAR
10 FT. GANJA PLANT
and give some dub a try:
MAD PROFFESOR
SCIENTIST

Trip hop was mentioned so try:
LAMB
SNEAKER PIMPS

Jurassic 5 suggests to me:

SURREAL & THE SOUND PROVIDERS
DANGER MOUSE & GEMINI

For the punk bands try some early 80's hardcore punk:
BLACK FLAG
G.B.H
DISCHARGE

For the chill/electronic/world bands try:

FAT FREDDY'S DROP
JOSE PADILLA
THE CAT EMPIRE

For Bright Eyes/Arcade Fire indie try:

OF MONTREAL
CARISSAS WIERD (intentionally spelt wrong)

I hope you give a few of these a go.
