The large crowd for Boomerang day two was significantly, and perhaps unsurprisingly, younger and livelier than those who turned out for Simple Minds.

The stage was opened by Bradley, a singer-songwriter who won a competition to perform. His raw, acoustic sound and accomplished guitar playing marked him as one to watch.

He was followed by alt-folk singer Nathan Ball, a spellbinding and talented musician, but his pensive, melancholic sound felt somewhat out of place in the pop-driven line-up.

Despite enjoyable sets from Rae Morris and Soul II Soul, it was clear that most the crowd was waiting for the two headline acts.

The Vamps got together after seeing each other’s music on Youtube, and their energetic mix of recent hits got the crowd going.

Their pop-punk spin on Taylor Swift was particularly enjoyable, and though their original songs were less engaging, it's easy to see why their young fan base is so large.

Jessie J packed her set with relaxed chat and earnest vocals, and in her more unguarded moments, her huge musical talent emerged from the slick pop.

Despite including big hits Price Tag, Do It Like a Dude and Bang Bang, it was an intimate, theatrical and elated performance from a giant of British pop.
