Non-Comprehendus is the debut album from the South Australian rock band Testeagles, which was released on 27 February 2000.[1][2] It reached No. 8 on the ARIA Albums Chart.[2][3] It provided two singles, "Turn that Shit Up" (July 1999), which reached No. 54 on the ARIA Singles Chart,[3] and "Underdog" (October).[1] The album was produced by Paul McKercher (You Am I, Spiderbait) with mixing by American producer-engineer, Ulrich Wild (Prong, Pantera, White Zombie, Grinspoon).[1]
Australian musicologist Ian McFarlane described the album as, "a heavy-duty mix of alterna-metal riff-rock, squalling sound effects, experimental electronic beats and samples, [the album] was certainly the most visceral album to chart in the Australian Top 10 since the likes of Nine Inch Nails and Marilyn Manson."[1] The tracks received attention on national youth radio, Triple J, with "Turn that Shit Up" listed on Triple J Hottest 100, 1999 at No. 66.[4]
The band were dropped by their label, Sony, soon after the album was released.
