Just a few months ago, Grateful Dead drummer Mickey Hart celebrated the 25th anniversary of his acclaimed solo album, Planet Drum. It seems that Hart’s work is far from over, as he was recently spotted in the studio with producer Michal Menert and String Cheese Incident drummer Jason Hann.

The news comes by way of Hann’s Facebook page, where he talks about laying down “15 tracks of drums and some electronic overdubs in a 24 hr period.” He also says that he got to hear recordings on the album from Zakir Hussain, Sikiru Adepoju, and Giovanni Hidalgo, all of whom are featured on Planet Drum and many other projects with Hart.

While there is no set date for this album’s release, we’re certainly excited to see what this incredible artist lineup has in store! You can see Jason Hann’s post, below.
