Future Artists
I was thinking of future artists, but this post is about the present day, so I felt like posting this here.  There have been several artists doing works intended to last for years.

John Cage was an avant-garde composer; one of his works was 4'33'', which was 4 minutes and 33 seconds of silence.

Another is a work known as As Slow As Possible.

It has been performed, and the performances last many hours. But one performance in particular may be of interest in the OA Universe.

Organ2/ASLSP (As Slow as Possible) is a musical piece by John Cage and the subject of one of the longest-lasting musical performances yet undertaken. Cage wrote it in 1987 for organ, as an adaptation of his 1985 composition ASLSP for piano. A performance of the piano version usually lasts 20 to 70 minutes.[1]

An organ in St. Burchardi church in Halberstadt in 2001 began a performance that is due to end in 2640. The next note will be played on February 5, 2024.

[*]Musicians and philosophers discussed Cage's instruction to play "as slow as possible" at a conference in 1997, because a properly maintained pipe organ could sound indefinitely. The John Cage Organ Foundation Halberstadt decided to play the piece for 639 years, to mark the time between the first documented permanent organ installation in Halberstadt Cathedral, in 1361, and the proposed start date of 2000.[9] The Foundation sells plaques commemorating the years through 2640 to fund the performance.[10][11]
The instrument
An organ was built specifically for the performance.[12]

[*]The Halberstadt performance started on September 5, 2001, with a rest lasting until February 5, 2003, when the first chord played.[14][15] Sandbags depress the organ's pedals to maintain the notes.[1] Two more organ pipes were added alongside the four already installed and the tone became more complex at 15:33 local time. The bellows provide a constant supply of air to keep the pipes playing.[16] On July 5, 2012 two more organ pipes were taken out, and two were in the organ. The note changed on September 5, 2020.[17] The performance is scheduled to end on September 5, 2640.

Presumably there are few or no high-tech cybernetic devices in the cathedral, so it is unaffected by the Technocalypse.  Maybe Gaia is impressed by the low-tech ambiance and allows it to continue.


AS Long As Possible (ASLAP) (2015–2017) is a 1,000-year long animated GIF made by Finnish artist Juha van Ingen.[1] It premiered at Kiasma National Museum of Contemporary Art in Helsinki on 28 March 2017. The animation is created in collaboration with developer and sound artist Janne Särkelä.[2]
ASLAP belongs to a group of art works for which extreme duration is an essential part of the concept, such as Canadian artist Rodney Graham's Parsifal (1882—38,969,364,735), which was based on an addition to Richard Wagner's Parsifal by Engelbert Humperdinck during the first performance thereof.[3][4][5] It was initiated in 1990 and in theory is playing for another 39 billion years – three times longer than the estimated age of the Universe.[3][4][5] Other well known examples are Longplayer by Jem Finer (of the Pogues) sounding from the Trinity Buoy lighthouse near Canary Wharf in London and the yet to be realised 10,000-year Clock of the Long Now by the Long Now Foundation in USA.[3]

The first ASLAP play back unit is included in the collection of The Finnish National Gallery and is playing and stored in Helsinki. The Finnish National Gallery has agreed to keep the animation playing until 3017.[12]

Longplayer is a self-extending composition by British composer and musician Jem Finer which is designed to continue for 1000 years. It started to play at midnight on 1 January 2000, and if all goes as planned, it will continue without repetition until 31 December 2999.

Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound machine. This new sonification – that is, the translation of astronomical data into sound – is being released for NASA’s Black Hole Week this year.

In some ways, this sonification is unlike any other done before (1234) because it revisits the actual sound waves discovered in data from NASA's Chandra X-ray Observatory. The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel.
