Not sure if cool and if not please remove.
I play guitars and piano for the past 25 years, so most of my life.
Got pointed in the direction of a new app that is being developed that allows people like myself to jam with friends or just random people, basically you get to play a track and other people join in and then you get to create a full track with various people and playing styles.
The reason I am putting it out here is they need people to contribute and spread it around so they can get it right.
the site is here:

They have a cool movie that explains it.
Cheers.
