I did not expect to see a Magma discussion on HN, haha. I saw them live back in 2015 and it was so surreal.
Then I saw them 2 years later where they played a much extended version of De Futura (and other songs). Great, too, but as a smaller line-up.
None other than Jello Biafra introduced them at a concert at the Fillmore not too long ago, saying how much he dug them. Now THAT was not something I was prepared for!
