i stumbled upon this, and found there are many more in many keys in a few other genres. hugely essential to practice your scales and fret board knowledge. its great to put this stuff practice to music, just makes the exercises much more enjoyable.. like i said its not just this genre of music, you can find many others. i loved laying down a bass line to this, and just experimenting.
i hope this helps other's.
