"I think that every band tries to mature their sound through their existence, you know?"

Adam Rich's quote suggests that bands naturally progress and mature their sound over time. He implies that this is a natural process, which it is something that all bands strive for. This might be analyzed as a sign of development and progress, as bands are constantly pressing themselves to produce new and innovative sounds. It could also be seen as an indication of maturity, as bands have the ability to take their sound to the next level and develop something that is more complex and sophisticated. Eventually, Adam Rich's quote recommends that bands are continuously making every effort to enhance and fine-tune their noise, which this is something that all bands need to strive for.
