[8] AllMusic's Heather Phares deemed it the group's "most mature album yet", describing it as an "inspired, eclectic mix of sounds and textures" which is enhanced by sophisticated arrangements and effective performances.

[2] Andy Gill of The Independent described it as an extraordinary album of "uncompromising, absorbing avant-rock" that resembles a "neo-primitivist garage band" playing the music of Henry Cow, Frank Zappa, Faust and the Residents.

[7] Cameron MacDonald of Stylus Magazine wrote of the group's "deft" experimentation with numerous genres and noted how the album "continues the band's previous excursions into tribal percussion and cartoon-core melodrama."

[3] Sam Mickens of The Stranger wrote that, on Tagia, "OOIOO's blissful-experimental-pop-as-hypnosis MO is purer and simpler than ever", highlighting a "a sense of gradual, natural, concerted development".

[10] A more reserved review came from Grayson Haver Currin of Pitchfork, who felt that "in small doses, Taiga is still inspired and moving, sweet even", but that over 58 minutes, the listener "gets sick sampling chunks from two-dozen flavors [of music]".
