Thee Silver Mt. Zion Memorial Orchestra (previously A Silver Mt. Zion, The Silver Mt. Zion Memorial Orchestra & Tra-La-La Band, The Silver Mt. Zion Memorial Orchestra and Tra-La-La Band with Choir and Thee Silver Mountain Reveries) is a Canadian band which formed in 1999, originating from Montreal, Quebec. They use a number of different variations of the name on different releases, but the group use the shorthand SMZ and their name is most often simplified to Silver Mt. Zion. Since their inception, the group has undergone almost yearly personnel changes. The band currently has five members following the resignation of three in late 2008.
The band has released seven studio albums and one EP, publishing them through the record label Constellation. Their debut album He Has Left Us Alone but Shafts of Light Sometimes Grace the Corner of Our Rooms… was released in 2000 and—with the exception of two tracks—is a purely instrumental record. As other records were created, their sound and membership progressively changed from a trio to a quintet. By the release of Horses in the Sky, the group became overwhelmingly vocal in its style.
The album Kollaps Tradixionales was released in February 2010. It consists of seven songs, three of which previously debuted at live performances. Another album Fuck Off Get Free We Pour Light on Everything was released January 2014.
Silver Mt. Zion's music has been described as "post-rock", though the band members are hesitant to use the term. Singer and guitarist Efrim Menuck identifies with punk rock ethos and aesthetic.
