In today’s edition of the weekly round-up there are three pieces by artists who have all been featured here before and for whom therefore introductions are not really needed. (Happily so, it turns out, as I have less time on my hands now than I should like.) Thus without further ado, in a Sunday sequence which is focused first in a retrospective-cum-reflective mood on the weeks past, and then turns around to prepare energetically for the next, a work by René Baptist Huysmans, “Glough,” with Michael Bonaventure on the organ, a song by Givan Lötz, “Test Me,” and an original composition by Jeremy Henry, otherwise known as the Haus of Glitch.
