I have trouble connecting with the folkier songs. Unlike, say, Simon and Garfunkel, I don't have history with Donovan and the time/genre gap is too hard to bridge. They just kinda bounce off me. On the rockier stuff though, you can either feel Jimmy Page's contribution, or hear the influence Donovan had on Led Zep (it's hard to untangle which tracks Page played on). Season of the Witch is, and the kids say, a banger. Overall - I think with a bit less sitar and a bit more guitar, this would have aged a lot better.
