Brothers Noel and Liam Gallagher have initiated legal proceedings against former Oasis sound engineer Huw Richards over his attempt to sell archival recordings of the band. Court documents filed in the High Court on Tuesday indicate that the legal action seeks to prevent Richards from auctioning off more than 100 hours of recordings, including soundchecks, rehearsals, and what is believed to be the sole recording of Oasis’s 1996 Loch Lomond concert.

Richards worked with Oasis from their 1994 debut album, Definitely Maybe, through to 2001. The auction, organised by Littleton Auctions, was scheduled for Saturday, with experts estimating the tapes could attract bids totaling up to £1.6 million. Alongside Richards, Littleton Auctions and Richards’s son, Owain, were named as defendants in the case. Owain Richards has previously commented that the audio quality of the tapes was sufficiently high to merit release on a live album, though both he and his father acknowledged that intellectual property rights would prevent any commercial exploitation by potential buyers.

The filing does not detail the specific allegations made by the Gallagher brothers. Along with Noel and Liam Gallagher, Sony Music Entertainment and Big Brother Recordings—the label founded by Oasis in 2000—are listed as claimants. No hearing date has been set.

Oasis, formed in Manchester in 1991, was among the defining bands of the Britpop movement. The dynamic between the Gallagher siblings, now aged 59 and 54 respectively, has long been a focal point of media coverage. Tensions led to Noel Gallagher’s departure from the band mid-tour in 2000, citing Liam’s volatile behaviour as a factor.

The brothers reconciled in recent years, culminating in a highly successful reunion tour last year that reportedly sold 1.4 million tickets. Plans for an additional series of shows next year have also been announced. Representatives for the Gallagher brothers, through Bray & Krais Solicitors, have been approached for comment but have not yet responded.
