The duo's third album, B.P. Empire, found them deviating a bit from their established psy-trance sound, experimenting with classical and Middle Eastern-influenced melodies and slower tempos. The 2003 double CD Converting Vegetarians took this genre experimentation further, designating one disc for more straightforward trance tracks and a second disc with tracks ranging from ambient and abstract electronic music to synth pop and downtempo. IM the Supervisor followed in 2004, and found the duo adding new production techniques and influences as well as an increased presence of vocals. The album was more accessible than previous efforts and became their most commercially successful release to date.
Following IM the Supervisor, Infected Mushroom relocated to Los Angeles, and began working with guitarists Thomas Cunningham and Erez Netz. The duo was ranked number nine in DJMag's Top 100 DJs poll in 2007, confirming their status as the most popular psychedelic trance act in the world. Infected Mushroom's 2007 full-length, Vicious Delicious, expanded their stylistic range beyond electronic dance music, encompassing hip-hop, rock, and Latin music. The album featured more guest appearances than previous albums, including vocals by Gilberto Cerezo of Kinky and Canadian hip-hop group Swollen Members, as well as the increased presence of live instrumentation. Arriving in 2009, Legend of the Black Shawarma (released in North America by Paul Oakenfold's Perfecto label) took their rock/trance fusion sound even further, including collaborations with Korn's Jonathan Davis and Jane's Addiction's Perry Farrell, as well as Infected Mushroom's remix of the Doors' "Riders on the Storm." In late 2011, Steve Aoki signed Infected Mushroom to his Dim Mak label. The group's first release for Dim Mak was 2012's Army of Mushrooms, yet another stylistic expansion, featuring dubstep, electro-house, and drum'n'bass tracks, as well as a cover of Foo Fighters' "The Pretender." The group then undertook a massive North American tour dubbed "The Unveiling," which featured an ambitious, overwhelming audio-visual setup. This was followed by another North American tour, "FungusAmongUS," along with guests the M Machine. Infected Mushroom released a collaborative EP called Friends on Mushrooms, Vol. 1 in early 2013, followed by a second volume later in the year. The duo also produced a track on Lady Gaga's 2013 album, Artpop. Friends on Mushrooms, Vol. 3 appeared in 2014, and a full-length titled Friends on Mushrooms, containing tracks from the EPs as well as two new songs, was released in early 2015. Later that year, Infected Mushroom released Converting Vegetarians, Vol. 2, which found them revisiting the psy-trance sound of their earlier work. They followed in 2017 with their 11th set, Return to the Sauce. ~ Dean Carlson, Rovi
