Jam (formerly Janine) Rostron previously played Brighton supporting her excellent W album in 2011.

Since then, a lot has changed, including her legal name which she has changed to be less gender specific.

But the most obvious difference from her Earsthetic performance at the Brighton Dome Studio Theatre was the growth in the size of the audience.

In a black outfit and round shades, at points – especially during opener Public Love – Rostron resembled Ozzy Osbourne, thrashing and gyrating around the mic stand with metallic intent. But the rhythms and beats that roused the most were those from the clubs, and which new single Human Drama had in spades. This was, Rostron admitted, its live debut.

The entire setlist was urgent and dance floor-oriented, but never once without a message – be that anti-misogyny, anti-patriarchy or just rallying against presumptions about the protagonist’s sexuality (it is “fluid like water”, if you were wondering).

Yet what Rostron delivered most strongly was her own vision, unobstructed by fashion or expectation.

Her growing, devout band of followers – perhaps larger here in Brighton than anywhere in the UK – knew this and applauded for it long after Jam had left the stage.
