I was aware of several of his tunes, but had never listened to an entire album. I’ve recently been working my way through our vinyl A to Z, and my wife had a couple of his. I was underwhelmed. A lot of the songs just seemed like “ideas” that were never developed and never went anywhere. At least they are short.
