Personally, I thought it was a jazz fusion band from the 70s featuring Wayne Shorter at one point.
But this connection is even better.
Weather Underground is the current working title for the fifth studio album from UK band Massive Attack. Artists currently believed to be contributing to the vocals for the album include Stephanie Dosen, Tunde Adebimpe, Hope Sandoval, Tom Waits, Dot Allison, Horace Andy, Mike Patton, Liz Fraser, Jhelisa Anderson, Damon Albarn, Patti Smith and Mos Def.
There is a movement in the works and I strongly support it. With all my might.
