I think it was renamed and repackaged after the first release, but my copy is ancient.
I also saw him and Hawkwind at Stonehenge in 1984 ( when he fell off the stage), so it isn’t just my vinyl that is ancient.
In any event, the point is that you are dead right: the man is brilliant, with a huge body of work that deserves much wider recognition. However, he also fits into the ‘musician’s musician’ category with (for example) Bert Jansch - when you turn up to a gig, it seems that most people there are also musicians, some vastly more famous.
Coincidentally, I saw/ heard a John Gomm gig a few months ago and non-guitarists like me were very much in the minority, so he may make it onto the list too - I bought the LP and the T-shirt.
I have that first Gryphon album - and a later one ‘Red Queen Gryphon Three’, which is a touch more ‘prog’ than the earlier one.
Also, I saw Gryphon play at the Union Chapel in 2016(?). Very entertaining.
An album I considered for this thread, which might be really too well known to qualify, is 801 Live.
Inspired by @frenchrooster …my original vinyl …Leroy Hutson The Man ( 1974) and Feel the Spirit (1976) Fine albums. At the time I worked with a very cool Jamaican guy who introduced me to alsorts. In return I got him into rock music.
Forever Changes , is I think much more appreciated in the USA than the UK , certainly one of my favourite all time albums, they changed tack afterwards , much heavier and dare I say it ? Losing their originality
