The Terror of Cosmic Loneliness is a collaborative album by Welsh singer Gruff Rhys and Brazilian musician Tony Da Gatorra.

[1] In a review for Drowned in Sound, Kyle Ellison wrote: "Unfortunately this doesn't make for the most coherent of listens, and for the most part this record feels half-baked.

Moments of genuine inspiration are difficult to find, which is surprising considering the pair's obvious talent and intrigue.

While the most fully formed song, 'In A House With No Mirrors', hints at the duo's potential, even this is fairly ordinary and the track feels incongruous with the sparser sounds found elsewhere.

"[3] Alex Wisgard of The Line of Best Fit stated: "The ten songs on The Terror of Cosmic Loneliness make up the strangest record Gruff Rhys has ever put his name to – this from a man whose back catalogue includes an electropop concept album about John DeLorean.
