The Brown Acid Caveat is the seventh full-length album by the experimental rock group The Tear Garden released on July 7, 2017 after starting a successful PledgeMusic campaign in August 2016. The campaign, which achieved 117% of its financial goal, allowed for the inclusion of a number of guest musicians including Dre Robinson and former Legendary Pink Dots members Ryan Moore, Martijn De Kleer, and Patrick Q. Wright. The album title refers to an announcement given to spectators of the first Woodstock Festival in 1969 to avoid "brown acid" -- a type of LSD reportedly associated with bad trips.
