i would rather have 'it' in the concert hall, where it can be less 'handled' than in the ballet school where many different talents brush it up. it prefers old bark that is generally more than 20 years old. this album was released as a bonus item included with the limited edition first printing of the windows version of angel beats! single-sided video discs did not appear to suffer from laser rot while double-sided discs did. jack was able to get an investigation launched. it is available with at least two different covers. (note: earlier data was not readily available).
