Those who caught Deaf Club on the BBC Introducing Stage at Reading or Leeds at the weekend will now be well aware of their powers. Their 25 minute set (highlights of which can be seen here) brought a stormy, bewitching atmosphere to the festival that swept far beyond the reaches of the Stage's limits.

Towards the end of the set, the London based Welsh group played Sunday and it was one of the many fantastic moments witnessed across the weekend. In person and on record, Sunday is a fiercely dramatic soundscape with rippling guitars, echoing drums and Polly Mackey's delicate vocals filling every second with tension of a cinematic scale.

The band, who originally released the track in February after the success of their debut EP Lull, head out on an eight date tour in November. You can find out more details on their tumblr.

Sunday is being played all week on Radio 1 and will be made available to download as part of Huw Stephens' free Introducing podcast from August 30th 2012. Let us know what you think of Sunday using the comments below.
