Guitarist Kim Thayil expects the record to be completed towards the end of the year
In an interview with the Seattle Weekly Thayil revealed that the band had recorded some of the album already but that they were still working on tracks between their live shows.
When asked about the release date of the album he said
"There's no timeline, except that our target - roughly - is early 2012. We are focused on this tour and these shows and we have a few dates in October, but in the interim, we'll do some studio work. We have a few more guitars to do and some vocals. And some of the songs are still being arranged.
"We want to make sure it's absolutely the most satisfying for us, and put the best foot forward that we can put," he added. "I would assume our fans will also get into it then."
The record will be the band's first new studio record since 2006's Down On The Upside.
