Can在1969年带着他们制作粗糙却令人鼓舞的专辑《Monster Movie》初次登场，这也是唯一一张由来自美国本土的歌手Malcolm Mooney主唱所有歌曲的专辑。 Can's debut is the only full-length, proper release to feature original vocalist Malcolm Mooney, whose free-form ranting is matched by a raw, aggressive dynamic unlike anything else in the group's canon; driving, dissonant songs like the extraordinary "Father Cannot Yell" and "Outside My Door" even owe a rather surprising debt to psychedelia and garage rock. More indicative of things to come is the closer, "Yoo Doo Right," a 20-minute epic built on the kinds of hypnotic motifs and minimal rhythms that quickly became Can trademarks.
