How to unlock the Hendrix Reborn achievement in Guitar Hero III - Definitive Guide
This achievement is a little glitchy, but keeping all your songs within the same "band" should make it work properly. All you need to do is enough to get by (3/4) on easy and medium. I suggest picking an easy difficulty and going for 5 stars on all the songs while you're there.
If you have trouble playing with the opposite hand, watch the screen in the mirror and they'll appear as you're used to seeing them.
