Bloc Party guitarist Russell Lissack will join Ash on their forthcoming UK tour.

The musician told how he was once in a tribute band to the Irish pop rockers, and can't wait to play with the band at a show in Japan and then across the UK, with talk he may also appear at some festivals with them over the summer.

He explained: "I've always loved Ash - my first-ever stage performance was part of an Ash covers band, so when they asked me to join them on their forthcoming tour I jumped at the chance!

"And it's not like I need to spend months practicing or anything. I remember quite a lot of the old stuff."

Ash - comprised of singer and guitarist Tim Wheeler, drummer Rick McMurray and bassist Tim Hamilton- have been without a second guitarist since 2006, when guitarist Charlotte Hatherley left the group after nine years as rhythm guitarist.

Russell - who has been in Bloc Party since the band formed in 2003, although they are on hiatus for 2010 - said he thinks it will be "weird" being part of another group.

He said: "I guess the only weird part would be spending so much time with people I don't really know. I'm not sure how that will work out, but we seem to have got on well so far."

Meanwhile Russell's bandmate, Kele Okereke, announced he will be playing a solo acoustic show as part of this year's series of Ibiza Rocks concerts at the end of August.
