So I have been playing, (second time around) for about four years now. I would consider myself an intermediate on most things I do. I play blues and classic rock mostly. I also finger pcik on my acoustic. There are two things that may hinder my status as a true intermediate. The first is the fact that I am not there yet with improvising, with the exception of simple blues. The other, which is the topic of this thread is, I play songs pretty well, (GT songs and other websites). I even make my own tabs at times. I can play the verses and the solos. But as soon as I put the backing track on, I lose it. I miss parts that I have practiced for months. Then I shut the track off and I am playing good again. I have an audience of none, so I can't say that I am nervous. A good example would be Tom Finch's Sweet Home Chicago. Anyone else have this problem? What do you do to end this frustration? Thanks.
