cellist Tom Cora in the early 1990s, resulting in the album Scrabbling at the Lock (1991) and the follow-up And the Weathermen Shrug Their Shoulders (1993). The album In the Fishtank 5 (1999) was made with Chicago's Tortoise, and on In the Fishtank 9 (2001) they collaborated with members of Sonic Youth and the Dutch improvisers Instant Composers Pool Orchestra (ICP). In 2009, after 30 years with the group, singer and co-founder G.W. Sok announced his departure from the band. Sok did so, believing he lacked sufficient enthusiasm to continue with the group, having decided to focus on writing and graphic design as well as singing in new musical projects with several other bands. His replacement is Arnold de Boer from the Dutch group Zea, with whom The Ex have toured and collaborated. In addition to singing, De Boer plays guitar and utilizes samples with The Ex. The Ex is the subject of a documentary, Beautiful Frenzy (2004) by Christina Hallström and Mandra U. Wabäck, and the concert film Building a Broken Mousetrap (2006), directed by Jem Cohen. In 2008 the band was also featured in the film Roll Up Your Sleeves, directed by Dylan Haskins. In 2011 The Ex were chosen by Caribou to perform at and co-curate the All Tomorrow's Parties music festival in Minehead, England.
