As many interview records, this is an item for the already hooked. If you have little or no reference to Nick Drake, this may be interesting, but otherwice it's a bit like knocking down open doors. It does also, given the "tracks" names indicate some musical parts. Well, there is none.
It's much better to read a good biography than buying this, in my humble opinion.However, if you're a die-hard fan of Drakes, it may be unmissable to you!
