Was anyone else watching the Alabama Shakes on SNL last night? I've been a fan of their album since it came out, and I think their bass player records some good lines. However, I was shocked to see (and maybe I'm wrong), that Zac Cockrell plays finger style with only his index finger. Anyone else notice this? He may have alternated on a couple of quick fills, but that's it. Are there successful bass players in the biz that do not alternate fingers?
