So, I'm back from the Sea Music Festival, and I've identified various artists whose albums I wanted to buy, but couldn't, because they weren't sold in the store. I can't understand why performers didn't have sufficient (if any) albums in the store.

Anyway, a web search turned up just one album by Jon Campbell. Is that all there is from him? If not, where can I find more?

I'll have to come back later with names of other performers whose works I couldn't buy.

Thanks in advance for assistance.
