This is "Quantum Rainbows", a beat tape on the blockchain. It was broken up into 4 shorter sections, which were released bi-weekly and could be collected individually. This audio NFT of the full 16-minute composition has been minted and airdropped exclusively for collectors who held all 4 sections by 23:59 CET on the 25th of March 2022. With this token you are also eligible to claim a copy of the physical „Quantum Rainbows“ tape that can be played back in any standard boom box or walkman.
