All the music, none of the dank. Three days of experimental music went down in Glasgow at the Arches back in mid-October of this year, under the broad banner of the Instal festival, and much of it has been uploaded for free download. One highlight (well, two) is a pair of pieces by Lee Patterson, both performed on October 14. Judging by a small photo on the Instal site, the 15-minute “Sparklers” was recorded with just that, the safe firecracker alternative miked for all its fizzy complexity (MP3). Patterson’s “Table Top Set” has a more diverse pallette, including “syrup, tiny bottles and boiling water” (MP3). More info at arika.org.uk.
