Dead Air is an exclusive-to-audio Doctor Who story, produced as part of BBC Books' New Series Adventures line, and the seventh entry in the series to be produced.
Written by author James Goss and read by David Tennant, it features the Tenth Doctor travelling alone.
A pirate radio station in the 1960s is threatened by an alien called the Hush, who kills everything that makes noise.
The Doctor and the radio DJs try to trap the Hush before it devours the whole planet.
In May 2022, as part of Record Store Day UK 2022, the story was re-released on vinyl.
