premise: Which again Awesome . Then my older sisters husband pulled out his guitar and jammed out for about 2 hours . He 's awesome when it comes to the guitar ( which he should be as he has a Masters in Jazz Guitar Performance ... ) , he 's in a couple different bands that play locally . I got him to play a couple Metallica songs , and ' Back in Black ' and ' Hell 's Bells ' . Why did I ask him to play Back in Black ?
hypothesis: This song would last 2 hours .
