Much to my embarrassment only yesterday I actually realised what Nirvana were actually singing about.
Listen to Nile Rogers on this track ..... wow ! To any other guitarists on here ( even really good ones ) ....forget about knowing the right chords , mute all of your strings , and just try to stay with his rhythm , and the pick action .... ....... I sure as hell can't do it ! ..... but I've only been trying for 30 odd years ..... that's what I tell myself anyway ...
