I've recently been exploring the wonderful world of Garageband. It's a fairly amazing production tool, and if you download the various expansion packs, you can literally have over 35,000 samples and loops at your fingertips. Are you feeling sufficiently dorky? I hope so.
Motown seemed like a logical place to start these experiments. It's pretty much impossible to mess up the likes of Marvin Gaye and Tammi Terrell.
This is a work-in-progress - stay tuned to hear the progression.
