Bob Mould has never seemed to have much interest in looking back. The bridges to a Hüsker Dü reunion were burned long before drummer and songwriter Grant Hart died in 2017; the notion that Mould might revive Sugar, the band who scored three unlikely UK Top 10 albums of ferocious alt-rock in the mid-90s, seemed ridiculous. But here we are: after three New York shows, Mould, David Barbe and Malcolm Travis are touring the UK and Ireland.

Some things have changed: the seething sea of moshers at 90s shows is now a placid lake of the nodding middle-aged. Travis, 73, seems to drum with the minimum amount of movement possible, wisely given the searing heat inside the Forum. Others haven’t: JC Auto, which closes the main set, remains brutal and churning, thrillingly intense. Mould still stomps in circles around the stage like a man furiously searching for his lost remote control.

Mould, arguably, is the man who brought melody to American hardcore punk, and Sugar continued his desire for big tunes and searing guitars. When he plays alone, it can be hard sometimes to pick out the melodies behind the trebly sheets of guitar, but the ballast of the rhythm section holds the tunes in place, and the pop smarts of If I Can’t Change Your Mind and Gee Angel burst out of the PA.

The songs sung by Barbe don’t fare quite so well – his voice is smooth and high and gets a little lost in the mix. You can hear he’s singing during Company Book, but it’s more a texture than a selection of words, floating atop the guitars. That same texture, though, adds depth to his harmonies, giving Sugar a warmth that not all their contemporaries could manage.

There’s no time for messing around, just a furious charge through 23 songs in 90 minutes, including two recorded for the reunion – Long Live Love and House of Dead Memories – suggesting that Sugar might stick around to do more than tour gen X nostalgia. We can only hope.
