MY Dad, his Brother (my Uncle) and I used to play Bluegrass together. We always wanted to add a drummer to our trio, but never found one that wanted to play Bluegrass or Country. A drum just adds that certain beat to a song that is missing when the other instruments are playing. We went into a nursing home to play for just an hour many, many years ago and after we played our second song, one really old man said, "Hey, you need a drummer."
