Yacht Rock a Dockumentary

begs the question: what is rock?

Follow up: when is rock?

Both salient questions, also both very much open to interpretation....

It takes a musician to parse out jazz/rock/soul/blues etc. influences on various bands, but I would characterize Steely Dan as a rock band with jazz influences. Given that so many of the 60's and 70's bands were heavily influenced by the early blues artists, would you make that same distinction with bands such as early versions Fleetwood Mac, The Rolling Stones, or The Who?

The lines are indeed blurry.

And I would call them a jazz-rock fusion band with jazz being very much at the forefront.....most of the musicians that have filtered through the band are jazz guys....

I would call Fleetwood Mac a folk influenced rock band and both the Stones and the Who (to a lesser extent, they were bluesy early on but went the concept route) rock bands with a blues influence....

I also find it funny that LZ is regarded as a early heavy metal band by some when half the songs they did in their prime were covers of old blues songs.....
