Importance of being relaxed  

... while playing of course. I was jamming with the band earlier today, and we were working on a song. We were having problems. We were over-concentrated. Trying to find certain parts and certain riffs for the song. Suddenly, the lead singer started cracking some jokes, then after a while, we all relaxed, started saying jokes and laughing. Suddenly, our hands started "running" on the fretboards and we started getting some ideas. At the end of the day, we found an intro for the song, a bridge and vocals over the bridge. Plus a second bridge.

I sat down and remembered that this happened a few times in the past also. Just think about it.
