Yes, reissues/other formats are considered a seperate āreleaseā
If you go to the release group page:
And hit āadd releaseā on the right hand side, you can fill out all the information from your CD version, release date, barcode, packaging etc. Then it will give you the option of re-using the tracklist/recordings from the LP release (just change the format to CD after selecting that option, and check the numbering etc).
Then youāre done! Should be pretty quick. Let us know if you need a hand.
@andmalc: It would be great, if you could scan the back side from your CD case. Mostly you can see the missing dates from this āback coverā. If you also own the booklet, many of us are happy to get additional informations about all the involved people. Thanks for your addition!
