Punk is musical freedom. It's saying doing and playing what you want. In Webster's terms 'nirvana' means freedom from pain suffering and the external world and that's pretty close to my definition of Punk Rock.
I do think I feel it but you don't think you are cause at a certain time you are no age but you don't think you are anything. You feel the life you have lived. I feel that. It's been a long fifty years.
