There's also so-called acidcore, which often has similar basslines but a faster tempo and the kicks like in hardcore. Quite popular around here in the squatting/underground scene. And for me, when the dj or live is the eact thing I like to hear (tracks which basically minute-long buildups into even harder and way more out-of-this-earth soundscapes), it blows me away more than any 'normal' acid track ever did. That stuff gets me in trance in no time.
