https://www.youtube.com/watch?v=lu9utvfumwM I didn't know Aphex Twin's XTAL is based off samples from a track from Steve Jefferies, Mary Carewe & Donald Greig called Evil At Play...but in a very cool way. But the original writer says it is 'morally wrong' and Richard D. James just lifted it wholesale... Gyu Beats looks into this, and discovers how complex and layered XTAL is, and also how murky the line is between original, remake and creation. It's a good video about these early productions (and I suspect the bass is echoed because he was using a four track or limited mixer and maybe could only echo the whole lot?) but shows the issues well about how sampling can be very creative - but it is a little shitty that with all that money. Aphex Twin never paid the guy for the sample.
