This has just reminded me how much of an influence Norwood Fisher and Muzz Skillings were on me - thay basically got me into 5 string. As for solos, well thinking back to my funk metal days, here are the solos that opened my eyes to what was possible when i started playing....
Fishbone - Bonin In The Boneyard
Living Colour - Under Cover of Darkness/Times Up (incredible playing!/Funny Vibe
Primus - *that* solo in Tommy The Cat, Fish On or Those Damn Blue Collared Tweekers
Red Hot Chili Peppers - Love Trilogy/Naked in the Rain/Aeroplane
Suicidal Tendencies - Send Me your Money....which leads straight onto...
...Infectious Grooves - Therapy/Stop Funk'n With My Head
Mordred - The Strain
oh and Iron Maiden - Run To the Hills
They all have a proper "solo" section, but I suppose you could argue that these were all pretty bass heavy to begin with!
