One thing to mention - it helps to keep in touch when your teenage son is a fully fledged mosher!
My lad is into proper 'shouty' rock - and I tend to be at the more melodic end of the spectrum, but we cross over in the middle on such as Linkin Park, Lost Prophets and the ilk.
Latest album ordered - Steel Panther - fully developed spandex and big hair metal band from LA - just like it used to be but fresh!
