Pendulum. Recording sessions for the album took place in fragments at various locations: Keenan recorded vocal tracks with her head in a cardboard box which gave it a "closeness and deadness that makes it sit in the mix a bit nicer," while drummer Bullock recorded drum tracks in a neighborhood church before overdubbing guitar tracks and additional arrangements. Haha Sound became their first charting album in the United States, reaching No. 8 in the Top Dance/Electronic Albums chart. While touring the United States to promote Haha Sound, the group recruited American drummer Jeremy Barnes to perform their live shows. Felton departed after Haha Sound to form a new project, Seeland, with touring keyboardist Billy Bainbridge (formerly of fellow Birmingham Warp act, Plone). Broadcast's next album, Tender Buttons, was issued in September 2005. It was their first album as a duo of Keenan and Cargill. On tour they were joined by Ash Sheehan on drums and James’s brother Bill on guitar and keyboards. A second compilation of B-sides and rarities, The Future Crayon, was issued in August 2006. Broadcast released a collaborative album with the Focus Group (aka graphic designer and Ghost Box label co-owner Julian House) called Broadcast and the Focus Group Investigate Witch Cults of the Radio Age in October 2009. The band was chosen by Matt Groening to perform at the All Tomorrow's Parties festival he curated in May 2010 in Minehead, Somerset, England. 2011–2013: Keenan's death and Berberian Sound Studio Keenan died on 14 January 2011 at the age of 42, following complications with pneumonia, which she suffered from after earlier contracting H1N1. Cargill, the sole remaining member, said in a 2011 interview with Under the Radar that a new Broadcast album was in the works, featuring vocals recorded by Keenan shortly before her death. He later said: "Trish left a lot of tapes, four-tracks and stuff, and I've been going through those. It's difficult, and I'm connected to it at the same time. It's wonderful, but I'm also feeling a sense of loss. The next thing I release with Trish on it will be more like a monument and a tribute to her rather than this obsessive thing I used to have about making albums." however, the album has not been released. Broadcast were credited with providing the soundtrack Berberian Sound Studio for the 2012 film of the same name; the soundtrack was released 7 January
