This is some glorious loud jagged drone, that in places puts me in mind of the band France and their fearsome amplified hurdy-gurdy. I may be putting my hand in my pocket for this one.
The Ecstatic Music Band is a trance-psych collective from the US West Coast. For the last thirteen years, the group has been performing and recording long-durational, high-volume, maximalist dronewerks on amplified acoustic and electric stringed instruments, employing tuning systems derived from the overtone series.
