Looking for a story lost in the quicksand of ASSTR. I think it was called Rock Princess, but no luck searching. 2 or 3 part story. Guy is in a band and is teaching a girl to play guitar. The girl is really good, better than the other guitarist in the guy's band. Winds up outplaying the other guitarist who gets booted out of the band. Set in the UK, I think. Any leads much appreciated.
