Greg Mendez has a shelved album concept that he says you can have if you're a songwriter. The plan was to center each song around the rhythm of a different car's turn signal, and the title of the song would simply be the car's name (so "2003 Honda Accord," for example.) It never came to fruition of course, but it illustrates Mendez's hyperfocus on his environment as he mines for song ideas. 

Mendez's latest album is Beauty Land.
