The first solo album by Roger Waters is The Pros and Cons of Hitch Hiking.
 Most pop and rock releases come in standard Piano/Vocal/Guitar notation format (and occasionally Easy Piano / E-Z Play Today)
 Albums of recorded sound were developed in the early 20th century as individual 78 rpm records collected in a bound book resembling a photograph album; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33+13 rpm
