I don't know if many people have this problem but I sure do... I can sit for hours and jam on my bass.. comes up with all sorts of badass licks that are studio/album worthy imo... however... as soon as i get the camera out to record my licks so I dont forget them and BLAMO... I screw up right and left... my hand becomes stiff.... VERY frustrating... like to the point where I am throwing stuff and breaking it because I get so frustrated. Now ive never played on stage but I can imagine that if I have this kind of problem with a simple recording, then when it comes time to play a gig... i fear this will happen. Any advice on how to overcome this? I'm sure it's some kind of mind thing (obviously). Any suggestions you have I will be open to.
