Here, the brothers pump out bubblegum pop hits laced with unlikely influences from reggae (Only Human, Every Single Time) to trap (Used to Be), while still throwing in that peak Jo-Bros sound and playfulness, as on tracks like Cool.
Of course, the play for radio hits doesn't always pay off as the experimental sounds don't always wash and songs like Strangers and Love Her start to sound generic, plus lyrically - given all they've been through - we could've (and should've) got a bit more substance out of them.
They touch on real life a little in tracks like the festival-ready closers Rollercoaster and Comeback but all too often songs are vague and lacking in any believable heart - a real shame given we already know their stories, we just need to hear them tell them.
