Liam Gallagher has unveiled his debut solo single, Wall of Glass, having debuted it at an emotional Manchester concert earlier this week.

Buoyed by bluesy harmonica and pounding drums, it’s a robust offering from the former Oasis frontman, who said he worked with Adele superproducer Greg Kurstin to give his forthcoming album more melodic heft. “I can’t write those fucking big songs. I’m limited. My verses are up there, but I just can’t do that next bit,” he told the Evening Standard.

As well as releasing albums with his band, Beady Eye, and working on his clothing company, Pretty Green, Gallagher has made his post-Oasis name with an amusingly forthright Twitter feed, often feuding with his brother and former bandmate Noel. The lyrics to Wall of Glass are similarly combative – there’s a possible swipe at a certain boyband as he sings: “You were sold the one direction / I believe the resurrection’s on.”

Rumours have abounded that Gallagher may reform Oasis in the wake of the terror attack on Manchester Arena, either at his solo shows or for part of Ariana Grande’s benefit concert this weekend.

The rumour mill was further stoked after a member of the Black Eyed Peas tweeted that Oasis would be appearing at the latter event. The tweet was quickly deleted and Gallagher, who is due to play a gig in Germany that evening, has scotched the news. He told Radio 1: “Mate, I don’t think so. I mean, I’m up for it but I think we’re booked for a gig somewhere.”

Gallagher did bring out former Oasis bandmate Paul “Bonehead” Arthurs at his Manchester gig this week, the proceeds of which were donated to the relief fund for the families of the victims of the attack.
