The Wall, bought the same days as my first CD player. Followed closely by Dark Side of the Moon, Songs From the Wood and the Grand Wazoo. After that I forget.
Followed closely by Dark Side of the Moon
Dark Side of the Moon reminds me of one way the vinyl was better, the album covers. The impact of that famous cover is really lost on a CD sized box.
The original cover had no writing whatsoever, no album name, no group name, nothing. The CD I purchased (many years ago) had what looked like a sticky label telling you it was "Pink Floyd ~ Dark Side of The Moon." Sadly it was not a label but printed on the artwork, further spoiling the effect.
