>He plays guitar, sings and fronts, and writes the songs? It’s his band.

Not that simple. One band I was in was started by the drummer. He was the guy with the connections who got the gigs. He was the diplomat who kept friction in the band to a minimum. He found all the people in it, including me, and put together a band that worked well. He didn't sing, front the band, play any instrument but drums or write songs.

We had a great singer who was a natural frontman and a great harmonica player. He didn't write but he arranged pretty much every song. He got most of the attention at gigs and was the guy everyone knew. It wasn't his band.

When the drummer had to go on hiatus the band didn't continue. It was his band in all our opinions.
