It doesn't necessarily follow that 'new' or 'inventive' ways of playing a bass are good, although they can, all, be tried at least. It may produce some kind of music when attacked with a blow-torch, or dragged across the stage by the jack lead, but I doubt that these extremes would catch on and become mainstream. I'm not suggesting that there's no merit whatever in 'slap'n'tickle' or whatever, but I certainly don't rate novelty over standard playing styles. I saw a TV spot once, quite a while back, whereby two reggae top knobs were being 'showcased'. The drummer (maybe Sly Dunbar..? I forget...) started tapping on the bass strings with his sticks. Very novel, and both had wide smiles, but it was an awful racket, for nothing. Original (at the time...), but of no further interest.
Just sayin'.
