So as was posted previously, Dave Grohl did indeed record drum tracks for QOTSA’s yet unnamed new album, due out in 2013. However, it looks as though Dave will not be hitting the road to play any shows with the band. You can read this (not so interesting) story on NME.com to learn more.
With Joey Castillo seemingly out of the picture (at least for the time being), no one knows who will be behind the drumkit when QOTSA goes on tour next summer. Their first scheduled show is currently in Brazil on March 30th, so a new drummer will need to be named fairly soon.
