Glassmasterer is Scottish-based Lewis Bigham, who has released a number of singles over the past few years in instrumental genres, mainly jazz and ambient.
This is quite an upbeat track which has some glitchy beats and some unusual ambient tones. It fairly burbles along, with some processed vocal samples, keyboards and other effects.
Catchy but quirky, with some other sampled sounds (milk bottles maybe) this is a distant relative of Boards of Canada, but the hooks are a bit more evident. Good lockdown listening while you tackle a spreadsheet, BM thinks!
