You play along with your favorite song or backing track and can't do no wrong. Your timing is perfect...you hit all the chords, and your solos are spot on... It seems like your moving in slow motion. You can't anticipate the next chord but your already there, and it's just perfect.
I love it when I have those days...Unfortunately today isn't one of them.
I can't keep time, I'm missing the chord changes, and my solos sound like someone skinning a cat.
Maybe I just need more beer. I hope your having one of those good days. :)
