"I would have to say I'm bored with the standard rock, guitar solos, but I've done it for five albums now, and this time I wanted to go in a completely different direction. I wasn't interested in showing off any more"

Kirk Hammett is revealing his wish to discover brand-new music directions. He is tired with the common rock and guitar solos that he has actually been betting the previous 5 albums. He is no more curious about just showing off his guitar abilities, but rather wants to try something new and also various. This could be interpreted as an indicator of maturation and also growth as a musician, as he is no more content to just repeat the same formula. He is seeking to challenge himself and also push the limits of his songs. This might be seen as an indication of artistic ambition and a wish to produce something one-of-a-kind and meaningful. It is a revitalizing perspective to have in an industry that typically rewards conformity as well as repeating.
