In the Sixties artists like The Beach Boys released up to 4 albums in one year. In England the standard practice was two albums and four singles a year. Around 1965 that changed to an album a year. This remained standard practice until the Eighties. When John Lennon took a break from 1975 until 1980 this was considered a very long pause. Nowadays many an artist releases an album every four or five years. When you consider 70 minutes for some cd's, you can regard those as double albums. But still, that's only an album every two years. Why? What happened? Do they get more royalties? Do they feel they have less to say? And which do you prefer? An 45 minutes album a year or a longer album every four years?
