I like the guy's approach; the creativity of constraint has always been appealing to me. Like a movie set in a single room. Thanks for sharing.
As far as my own stuff goes, I play guitar and I sing. I have recorded and published two albums of my own songs so far. It's an interesting process. I want to fit the structure of the song I set up for myself, but I also want to be authentic and honest. It's a delicate balance.
