CD: 1996 PRW (Brazil)
There are gatefold and single sleeve versions of the LP. My current copy is the PRW release, which was licensed from EMI Argentina. The first side is clearly taken from vinyl, whereas the second seems from master tapes. So unless the 2007 EMI release has found the masters, the sound will be suspect. Most original vinyl I've heard isn't much better either. Too bad really. All the CD's do include a rare 45 single from 1975, and demonstrates Alas in more compact form.
