The second LP features Can's more avant-garde efforts, with Roni Sarig, author of "The Secret History of Rock" calling it "as close as it ever got to avant-garde noise music." Featuring Holger Czukay’s tape and radio experiments, the tracks "Aumgn" and "Peking O" have led music critics to write that "Tago Mago" is Can's "most extreme record in terms of sound and structure." "Peking O" made early use of a drum machine, an Ace Tone Rhythm Ace, combined with acoustic drumming. "Aumgn" features keyboardist Irmin Schmidt chanting rather than Suzuki's vocals. The closing track, "Bring Me Coffee or Tea", was described by Raggett as a "coda to a landmark record."
