Hi PhilMH,
Yes, i see where you're coming from, but, Discogs seems to think that the appearance of the little cherub on the record indicates the label Angel Records, even if it has no text beneath.
See here (read "show more"), in which case, shouldn't it then just be be Angel? (if we are going to ignore EMI being the parent as you suggest)(also see LC0110 label code).
I would just call it EMI, Greg, as the word Angel doesn't actually appear anywhere - that was typically only used on releases in the Americas and Far East. Where the EMI logo appears in conjunction with another recognised label brand like Columbia, Parlophone, HMV, Stateside, Capitol, etc. then just use that label brand, and not EMI/Columbia, etc; the EMI logo was only used to indicate that the label was part of the EMI group, and EMI was only a label where no other label logo (as distinct from series logo) was present.
I have entered this one as Angel / EMI, as, i don't think there is a "EMI Angel" label, i.e, there is an "Angel" and a "EMI", but no "EMI Angel", therefore, the 16 US entries on Classical World under "EMI Angel" should be re-labelled as "Angel / EMI" as far as i can see?, to correct. ("Laser" is the series name btw)
