Bladder Flask was created by the Rupenus brothers, aka The New Blockaders. Bladder Flask and their ilk were spiritual forefathers to today's "Clicks & Cuts" generation. Incredibly, this sounds as fresh and startling today as it must have sounded 20 years ago.Their only album ' One Day I Was So Sad That The Corners Of My Mouth Met & Everybody Thought I Was Whistling' was released in 1981 in a numbered edition of 500 on the obscure Orgel Fesper Music (001) label , the album is comprised of two 25-minute side-long tracks of extended Dadaist reverie, a sublime mixage of musique concrete and instrumental collage.
