NICE find. Point is, dicking around with tunes and mixing tunes is just playing – just like any game, it’s trying different stuff.
I daresay there’s any amount of TP tracks that haven’t seen the light of day. Only the best make it to studio release. Studios are helpful for tuning and mixing the samples, but the speed they play and the cuts are very much instinctive – all the bits have to be cut to size before you play in the studio. That’s down to practise and ABOVE ALL – self confidance, KNOWING that the bits sound good together. Takes a long time, lot of patience, lot of practise, not letting the knobbers tell you that “you’re not good enough”, that “you can’t do it” – because YOU CAN LEARN ANY SKILL IF YOU WANT IT BADLY ENOUGH.
