Acclaimed singer-songwriter Dan Whitehouse has been in a transparently reflective mood with three albums all themed around the physical and metaphorical nature of glass. On The Glass Age, produced by Swedish multi-instrumentalist Gustaf Ljunggren and inspired by keeping in contact with his young son living in Japan, he explored how, in terms of communication, both positively and negatively, we have become a screen-fixated society exchanging virtual emotions with an emoji or a coded text, our smartphones as indispensable an appendage as an opposable thumb. As the song Campfire succinctly puts it, “When you change the way you look at things/ Watch the things you look at start to change”.
