There was an ICO for Tao (originally XTO) back in 2016. It was done before the major ICO hype set it and it was done in a legally compliant way that did not count as a security, making it a rarity.

However, the FanMix.com platform will include "IAOs" (aka Initial Artist Offerings) for musicians - they have a large number of artists already onboard ranging from no-name up-and-coming artists to established big names.  Each artist token will only be tradable against Tao and so each one adds to Tao's value.

Make sure to read my posts upthread for more details, and feel free to ask any questions you may have.
