Big Dada / 'Nothing2Step2' is a bonafide electronic pop anthem that vocalist Isis – her tongue only half in her cheek - refers to as her "Madonna moment." Over another chunk of hugely muscular, hugely emotive electronic dance music from producer Grahmzilla, Isis shows – having proved she can rap fast and slow, soft and loud – that she can really sing, too. As the bass lines swoop up and up, Isis delivers a classic love song – full of rejection and disappointment but also the strength to carry on. It's a superb performance which shows why Thunderheist are more than 'just' a club act (though this is going to work on the dancfloor, too)
