So far so good, but the developers of the project are concerned about the long term continuation of the piece of never repeating music. Although a computer is currently performing Longplayer, the project developers are aware present day technology will one day be obsolete. For this reason, they are seeking a non-technological and nondigital way of ensuring the survival of the composition for the next 990 years. The developers are experimenting with alternative performance methods from mechanical, non-electrical devices to human performance.
In its section of 'Survival Strategies', the Longplayer project website asks, 'How does one keep a piece of music playing across generations? How does one prepare for its technological adaptability, knowing how few technologies have remained viable over the last millenium?'
Beyond suggesting a number of mechanical and technological possibilities, the developers believe Longplayer will only survive if people are interested in the survival of this ambitious scheme, akin to launching a probe deep into space on an unknown journey. With it being nearly impossible to predict how technology will change within even the next ten years, live human performance may be the only way of guaranteeing the continuation of Longplayer through the millennium. The first live performance of Longplayer was held in London's Roundhouse in September 2009.
