I think it´s a good advice even if playing gigs or anything similar is not in our plans. Play AND practice like if it´s in a live situation. I think it will also be good for when recording. It happens to me that when I´m "practicing" I do it ok, but the moment I push the "record" button, I screw it up and make mistakes, because I want to do it "right and perfect", same as if I was in front of an audience.
The last time I played "for an audience" was on september, when I played "Hotel California" for my wife on her birthday - it was a request from her -. There were only family members that night: my wife, our son and his girlfriend - 5 years together, so she´s not a stranger, she´s like family - and a niece, who is like our daughter. There were no strangers in the room, but I was nervous and sweating, and yes, I made several mistakes that I didn´t make when playing and practicing the days before.
Now, of course, I played like a god according to them - how can you remember to play all those chords and notes and that long solo? -, but in my mind I was counting all the mistakes haha, and gave myself a score of about 67/100. When I was practicing, I think I was close to 90/100 according to the upper limit I imposed to myself; in other words, I didn´t intend to play it 100% original, no way I could do it, but close. I built a track that is a mixture between the studio record and the 1977 live record.
I still have it on my list of "songs I want to record", and now I practice like if it was in front of an audience, standing most of the time. I´m doing much better each time, although I still know that I don´t feel that comfortable plating in front of other people, all the more if it´s only me. If I were playing with other persons I know it would be different, like when I played at church years ago; in the end I felt much better and less nervous.
So, that´s it. Let´s not play "too comfy" in the hope of building some strengh and, finally, play with more confidence, at least in my own case.
Finally, following the "pics or it didn´t happen" rule, here you are. My wife with the green dress, our niece and our son´s girlfriend on the floor, and my son recording the video. No prizes for guessing who´s the moron playing guitar!
That way I "travel" while playing.
