Darkening Violets was issued originally as a CDR (never an official or proper CD release) and was quite difficult to get hold of (pre-streaming days). Some copies had playback issues and the silver play sides did have marks and scratches on some copies. No idea who made it though. It had a dark mauve / violet cover with a typed track list on the back. It was made as a light hearted repost to the Fading Yellow series by pointing to the more progressive end of 60s music which was not that well reissued at the time.
Greg,Clown can sound like Audience in my opinion,not early Audience of the first 2 album Audience(69)and Friends,Friends,Friends(70),but the final 2 House On The Hill(71) and Lunch,certainly not as good as Audience,but i do think Lord Of The Ringside is one of their best numbers,and they do have quite a few others that i feel are as good,but i do find the use of sax can be irritating in prog or psych infused albums,but if this came out on cd,i'd buy it,as theres enough good material with that early 70s sound i like for me to put down some notes.
