The Dragons debuted their euphoric, aphorism-loaded brand of rock almost a decade ago, at a time when the genre’s rapidly diminishing command on global charts was already a hard reality. Performing a career-spanning set list amidst their biggest supporters, the band proved why they’ve become the de facto resurrectors of rock today. The four-member band launched their fourth album, Origins, at a special show on their home turf of Las Vegas recently. But that’s probably not surprising when your global fan following runs into millions. In the Imagine Dragons scheme of things, even an intimate invite-only concert features no less than a thousand people.
