This Australian duo rocket into the arena dominated by Girls Aloud, Saturdays and Avril Lavigne with their second album.

They hardly pause for breath over 15 pop and rock songs bubbling with both attitude and catchy hooks.

The two sisters can sing pretty well too, another bonus that helps lift this album well above the average.

Infectious single Untouched is the best track but there are very few poor tracks amongst the punk-fuelled pop.
