Richard Skelton is a British composer and sound artist, better known for the project The Inward Circles. One year after Border Ballads, he’s back with a new album titled LASTGLACIALMAXIMUM which is out now via Scottish label Aeolian. According to the press release, it is an album of recordings for the landscape of the British and Irish peninsula as it lay most recently under ice. The general consensus among glaciologists is that the British and Irish Ice Sheet attained its greatest extent — the so-called ‘Last Glacial Maximum’ — between 27 and 21 thousand years ago.

The shifts in timbre and texture between succeeding recordings on this album is imitative of what are known as ‘Dansgaard–Oeschger events’ — rapid cycles between cold and warmer climatic conditions during the last glaciation. Listen below.
