There is a spontaneity and rawness to the Spocks Beard albums. The other side to the coin is that his solo stuff sounds a lot more polished and the musical ideas seem more complete or 'finished'.
Interesting, can you elaborate on that?
I think what he means is that the first 6 (especially the first 3) SB albums are pretty fresh, and for their time, were unlike any other prog band. Neal's sound was exploratory, not a lot of re-treading of ideas that he would grow comfortably into (things that made him a bit well-known, like multi-part epics with reprised themes, the occasional Spanish/Flamenco guitar section, and multi-part vocals), so a lot of the songs vary in theme, feel, sound, genre, and even among the first three albums, you hear a different sound from song to song but are all still identifiably (is that a word? lol) Neal's writing.
Even the debut is one of his strongest albums, especially having worked on it some years prior to recording and releasing it. The songs sound raw, but also polished, very complete and whole, but with that early 90's hard rock tinge that gives them a unique heaviness to them that isn't tied down to heavy metal or prog metal. To contrast that, though, there are some delicate moments. Listen to a song like "Go The Way You Go" or "Walking On The Wind", and you can understand how almost schizophrenic his music can be.
EDIT - It's kind of like diving back in time to a creator's early works. There's always that sort of "awe" and "magic" in hearing what they created before their works became more streamlined and polished. Neal's early work with SB is truly magnificent, and even within those 6 albums, he streamlined his writing, all the way up to V and Snow, two of his best albums with SB IMO.
If you've not checked out ANY of those 6 albums, I say definitely go in release order, just to get a sense of his chronology as a writer and performer. I doubt you'll be disappointed, especially if you already enjoy almost all of his post-SB solo albums, but do NOT forget his two solo albums released during his time with SB - the self-titled debut and
It's Not Too Late, the former of which features a 20-minute, 4-part epic!
