releases and being featured on compilation albums is not, in my best opinion, a candidate for speedy deletion. In order to meet the A7 criterion, the article must give no "indication of why the band is important". The albums and compilations are, at least, an indication. Whether or not the band then meets WP:BAND is a separate question, but that is not to be handled by a speedy deletion, but by WP:PROD and WP:AFD.
