I've got the upgraded 'Psychedelia' CD box set on 'Rubble' (Particles)issued last year and it still just lists them as unknown groups. The booklet has no info on them other than that both are acetates in poor condition so presumably nothing much written on the labels.
Yes, the 4 x vinyl comps came out on Tiny Alice originally with their own sub-titles but the generic series title of 'Psychedleia'. Then they were put out as 2 x LPs on 1 CD as 2 x CD volumes of Hen's Teeth. These in turn were re-mastered and put out as a card sleeved clam box set 'Psychedelia' last year with the addition of a fifth disc reissue of ther old 'Mynd The gap' bootleg comp.
