Soundgarden are looking at the possibility of making a deluxe 25th anniversary edition of Badmotorfinger, says guitarist Kim Thayil.
Soundgarden plan deluxe Badmotorfinger
Kim Thayil talks up extended version of 1991 classic to mark 25th anniversary
It would follow the 20th anniversary version of Superunknown, released this week – although it won't happen until 2016.
Thayil tells Billboard: "We have discussed giving the treatment to Badmotorfinger – there are some B-sides, there's some live material, and I believe they may be rehearsal material.
"Badmotorfinger had an impact with listeners, but also with guitarists, drummers and singers – people who started bands. It definitely deserves the same kind of treatment we're giving Superunknown."
Meanwhile, Thayil admits his long-planned compilation of B-sides and rarities is still something he wants to do, but the band have other priorities.
He says: "I've been talking about that since the mid-90s. I thought when we got back together we'd start on that project. But first we did the retrospective best-of, then a live record and then a new album. These tours came up and now Superunknown.
"The B-sides and all that stuff will be compiled in the future into a separate, standalone record."
Superunknown is be the first record to be released in a new headphone audio format called DTS Headphone:X. The 11.1 surround mix will be available from creators DTS to those who purchase the super deluxe edition of the re-release. Hear the Headphone:X version of Spoonman via the Soundgarden website.
The band are gearing up for a US tour with Nine Inch Nails during which they'll play before Trent Reznor's outfit. They return to the UK on July 4 for the British Summer Time festival in London, alongside Black Sabbath, Motorhead, Faith No More and others.
