I do believe that enduring geological features are important, though I don't think I can be clear about exactly why.
I have done a bit of recording and the songs are available on iTunes, and I've got some nice comments. It's something I enjoy doing, but I'm not looking for a singing career any time soon. As long as one person gets enjoyment out of it, I'm happy to make it available.
A lot of times, when a band finds success with a certain style or sound, they have a really hard time breaking away from that to grow as artists.
