A I A: Alien Observer, along with A I A: Dream Loss, received an honorable mention on Pitchfork's list of the best albums of 2011.^[3] In 2016, Pitchfork ranked Alien Observer at number 21 on its list of the 50 best ambient albums of all time. Staff writer Kevin Lozano wrote: "Liz Harris’ voice has the ability to leave you dumbstruck, speechless, just plain wrecked. It’s so beautiful, it’s almost mythic. Her hums, the barely audible whispers of words, the repetitions of phrases—they are often phantom presences, conjuring spooky action at a distance. [...] Harris stretches her voice into a ghostly chorus. Alien Observer feels material and visceral, but it retains her sense of mystery and emotional resonance."^[4]
