Billboard recently spoke with Isis' vocalist Aaron Turner about their upcoming tour with Tool:

This is the first type of thing we've done of this magnitude so that's a little bit daunting but also exciting. We're all very curious to see what transpires and how it all goes.

Turner also discussed the band's forthcoming DVD and album:

Maybe we're over-saturating the market and people won't buy the DVD and lose interest and not even follow up with the album. I think we're always a little bit more pessimistic or maybe just realistic in that sense that we never count on anything. We're just going to continue doing what we do and hope there are a few people out there at least who are receptive to us.
