It's any musician's dream to find a sound that is all their own. Once you hit upon something that you've never heard before, you want to go out and share it with the rest of the world. At the same time, that identifiable sound does tend to get a bit boring after years and years of playing.
Music is an ever-evolving thing. For as much as people want to make their millions off of nostalgia, there's always going to be those willing to push the genre forward and stun the listening public. While there are plenty of phenomenal bands who make a fortune off the same style of song (AC/DC, etc.), some artists prefer to see their musician as a reflection of themselves at the moment instead of just a job to do.
Rather than just slogging away at the same riff over and over again, these musicians have stepped up to the plate with something new every time, whether it be with different instruments or a different mindset to creating.
Most musicians wouldn't have the guts to do something this bold, but when you have a firm grip on your craft, most of your fans will be willing to go along for the ride.
I'm just a junkie for all things media. Whether it's music, movies, TV, or just other reviews, I absolutely adore this stuff. But music was my first love, and I love having the opportunity to share it with you good people.
