Musicians, Please don't say this (whatever it is) is only for musicians. I'm not talented musically, can't play a lick, (trying to learn), but I feel exactly what your talking about. Like Bert, I feel it mostly when I dance. My body is an instrument and I join in the out-of body experience with whatever musician is calling me.That is exactly what it is to me. It's almost orgasmic. (Hope that's not a dirty word here)
