This thread, in my humble opinion, is exactly the same as all the other threads which say "Where have all the good things that i like gone and why do you all like rubbish music" or some such.
All these threads are full of people listing all their current inspirations highlighting the fact that the OP simply has a different taste to everyone else.
So the example in this thread is Argh saying that the only person to take slap onwards and upwards since Larry Graham is Bill Dickens, now in my opinion, however technically adept Mr Dickens is, it's some of the most unmusical bass playing I've ever come across.
I could list all the bass guitar (4, 5, 6, 7, upright, piccolo et al), programmed bass, no bass music that i think is inspirational and moving things forward, but because the whole thing is so subjective, it's pointless!
I'm not actually bothered about how many strings we can fit on a bass, or how fast we can go, i want to know how we can contribute better to music, its been mentioned a billion times, but its the song that matters, not the individual instruments..........IMO
