CDs became the dominant medium right around the time that I was first getting into jazz, and I remember reading music critics talking about the duration of the format, wondering if a 75-minute (or more) album experience was too long. At the time, I thought: "What's not to like? You can just turn it off if you lose interest, right???"
As I've grown older, I suppose my thinking has changed. Partly, it might just be that my attention span has grown shorter -- no doubt about that. (For me, this is true of both music-listening and reading. Age has a way of making that happen. ) But I think the evolution of my thinking is attributable to more than that.
I'm beginning to wonder if an ideal album duration might be more like 35 to 45 minutes -- the length of an LP -- instead of the 65 to 80 minutes that's common with CDs. Of course, this assumes that a listener is still interested in sitting down and listening to an "album" as a cohesive, unified experience -- rather than just listening to a series of tunes. I know that "album listening" is WAY less common these days -- but it's still my model for thinking about recorded music. If someone asks me for a musical recommendation, I don't think about single tracks. I'm almost certainly going to recommend an album, regardless of format -- whether it's a CD or LP or download.
A possible analogue: A movie that's longer than 2 hours better be pretty darn good -- or your average viewer is going to lose interest. The industry has settled on a convention that says 100 minutes or so is about right, a good movie length. I'm wondering if an 75-minute CD is the approximate equivalent of a 2.5 hour movie. Sure, it can be done. But it better be some DARN good music; otherwise, something is lost. It's hard to maintain cohesiveness and momentum during an experience that goes on for too long. So, just like a fidgety theater-goer in an over-long movie, the music listener loses attention, the mind wanders, and some of the power of the music is sapped.
One last thought: I bet there are some long-time jazz fans who were listening to 78s and felt the same way when LPs came along. "What?!?!? 35 minutes is too long. Those soloists are just dragging on forever!" I realize that. Who knows what's best; there's probably no such thing! I just wanted share some of my reflections on this interesting intersection between our experience of music and technology.
So... what do you think?
