When you buy an actual physical CD from a band you want to support that doesn’t have their music in physical stores, they often include a thank-you note, which is a charming bit of memorabilia.
‘Wintergatan’ is a band from Sweden. Martin Molin is the composer of (all?) their music, and the designer/builder/operator of the musical Marble Machine in this now classic YouTube video. He is currently working on the next generation Marble Machine X, and posting videos of the whole process. I decided to buy a physical copy of their 2013 album to support the process while they can’t get into the studio to record their next album or go on tour.
Such exciting things come out of musicians these days, if you ask me.
