Shok, one of the nice people who occasionally makes music for my animations is doing a contest to remix a track by one of his bands, 'Zeitmahl'.

If you fancy having a go then you can download the files to join in from about halfway down this page:

You know, i'd love to get into remixing... Both the normal sort of thing and my own twisted delusions of what people will dance to:
One of the ones I would like to do is a remix of birdsong.
And i'd like to remix most of the Classical favorites (ie Pachelbel's canon and Beethoven's Moonlight Sonata)
