Definitely easier to earn cash doing all covers particularly when you play in a city with no real scene and/or crappy/limited choices for venues such as my city. Hell even in a music haven such as Atlanta, etc. its not easy to do original songs but much hard in smaller cities. Also some musicians just arent ready to take a risk.
However I saw Woven Bones in one of the best venues located in Birmingham, AL. Played all original music and I was one of 8 people at the show. Disappointing.
