There are two artists called Glass Isle.

1) Glass Isle are: Zuleika AvTes and Natalie Williams. London, UK. Although you hadn't realised you'd left the mainland, you are aware of the subtle change in geography. They are busy working the land, disassembling, reconstructing, reconstituting the abundant raw materials from the local earth and air. To walk the perimeter will take you just over an hour, but you are welcome to stay for longer. https://glass-isle.bandcamp.com/album/mm078-glass-isle

2) An indie rock band from Los Angeles, USA. On hiatus since 2011.
