The clip, which spruiks Armenian national pride, looks low-budget but feels like it could have been directed by dark fantasy master Guillermo del Toro. In it, spooky antique family portraits are interspersed with Genealogy's gorgeous leather-clad members leaping about a barren icy landscape that appears to be located inside a house.

Crucially though, O'Doherty's towering voice provides the backbone of the song. In a live performance she has the potential to lift Don't Deny beyond the realms of beige pop into a classic moment of unforgettable Eurovision bombast.

O'Doherty is a colouratura soprano (a singer whose role is to ornament a melody) and a very good one. She was a finalist in the Australian Singing Competition Mathy Award in 2007, also won the ABC Sym­pho­ny Aus­tralia "Young Vocalist" award that year and was the first recipient of the Australian International Opera Award in 2008.

"Armen Martirosiyan, the composer for our song ... showcased our unique voices and captured our individual styles brilliantly in the song-each of us add something very special to the song and I'm thrilled to be representing the 'operatic' element," O'Doherty told Fairfax.
