Tempo is a three-CD set recorded live during a four-hour performance by Mural at the Rothko Chapel in Houston, Texas, in 2013. Following the group's 2011 album Live at the Rothko Chapel, this release shows the group expanding into a much longer form. Mural consists of Australian windplayer Jim Denley and Norwegians Kim Myhr (guitar) and Ingar Zach (percussion). They first performed in 2007 in Madrid, and have performed live around the world since. The trio has released two critically acclaimed albums. After two successful concerts at the Rothko Chapel and a CD on the Chapel's own Rothko Chapel Productions, the trio visited the Chapel for the third time in April 2013. Wishing to challenge traditional concert formats, they decided to play a four-hour long performance in the Chapel. The result was so satisfying to them that they decided to release the music as a three-CD set. This is an expansive and patient form of music, far beyond any traditional entertainment formats. In an abyss of time, Mural's music is not only elevated to another level; one could say that in these long durations, it finally comes into its own. Rothko's paintings in the Rothko Chapel can be seen on the front cover of the release. Jim Denley: wind instruments; Kim Myhr: 12-string guitar, zither; Ingar Zach: gran cassa, percussion.
