Other reviews stated:  "It’s a stunning collection that demonstrates exactly why she’s one of our most exciting musicians." "O Vertigo! delivers everything we have come to expect from a Kate Miller-Heidke album: impressive vocals, unique style and a willingness to push the musical boundaries to create a fun and quirky album." "Kate Miller-Heidke is an example of true success... Kate outdid herself with this album and we cannot wait to see where she goes from here." "There are so many things to like about this record. Even if you’re a little put off by the impressive but admittedly still kinda dorky soprano gymnastics, Kate Miller-Heidke has covered such an expansive surface area of the current pop landscape on O Vertigo! that without any pandering, there’s something for everyone. Her flawless delivery and world-weathered yet unbreakable confidence shine on this collection with a vision that we may never have seen come to fruition at Sony. She took a big risk, but O Vertigo! is in itself the even bigger reward she richly deserves."
