I’m writing this post from the breathtaking atrium of the Milwaukee Art Museum, enveloped by the sound of Kevin Rank performing Blues for Gilbert on the vibraphone as part of the 2014 fresh inc festival. All around me are museum-goers, children, families, staff, couples – all of them taking a pause in their day to wonder at the sonic possibilities of this instrument, to take in the rocks, the waves, the seagulls as they swoop above the lake behind the performer.
