Not exactly my specialty, but when you speak of "epileptic fit" Ornette Coleman comes to mind. His classic albums are "Change of the Century" and "The Shape of Jazz to Come" but these are mostly sax albums with other instruments in the background. Jaco Pastorius lays down some wild and fast bass on his solo albums and with the band Weather Report. Someone already mentioned great albums by Herbie Hancock. Miles Davis has "Bitches Brew" and "Tribute to Jack Johnson" among others but I think you're looking for spicier salsa. There's also a guy by the name of John Coltrane - I hear he's pretty good.
