Rummaging around in here I discovered I still had a YouTube account, from the days before it became the quagmire of advertising and tracking it has become, which lead me to this old post from a decade ago:
The iPad was a mere one year old at the time but was already showing signs of its potential for making interesting noises. I suspect the missing video was for an, alas short lived and no longer available, app called Konkreet Performer which was an early attempt at new ways to interact with sounds on iPads:
Things have evolved over the years and today you have AudioBus to pump sound between apps, AUM to connect and mix instruments and effects and countless apps like TouchScaper and SoundScaper and even some that are not called somethingScaper. Although Smule still have some apps available their MadPad has also vanished; as has the Levenshulme Bicycle Orchestra.
The other video in that old post was a young Frank Zappa performing on a bicycle during the Steve Allen TV show in March 1963. Many years ago I read about this but who could imagine that decades later and thousands of miles away you can sit on a sofa with an iPad watching the video and also learn how, in late 1962, the young Zappa would hang out in Don Preston‘s garage improvising soundtracks to various film clips. Preston had a range of junk percussion ‘instruments’ he used including a bicycle.
