The triumph of bedroom pop

I must have been about 16 when I got my first Portastudio. The compact home recording unit had first been introduced by Japanese electronics firm Teac in 1979, offering unprecedented multitrack dubbing to the bed-bound amateur musician. For a little less than $1,000, you could record four separate tracks of instrumentation — as much as the Beatles had when making Sgt. Pepper — on an ordinary cassette tape. By the time I got my teenage hands on a four-track machine of my own, that price had come down by an order of magnitude. It was a chunky little unit in pigeon blue with just two microphone sockets and a small handful of mixing dials for volume control and stereo panning. Anything you fed into it would be squashed and smudged into its limited dynamic range and smeared all over with a waterfall of tape hiss. But to me that little box was magic.
