Small guitar effects pedals in the late 1950s distorted and modulated electric guitar signals, beginning a new era of music. In the late 1970s and 1980s, electronic instruments like synthesizers came to dominate genres like synth rock and electronic rock. Bands like Kraftwerk and Depeche Mode established signature electronic sounds through seminal albums in the 1980s that influenced mainstream pop and rock. Depeche Mode gave a powerful concert in Bogota, Colombia in 2009 that was celebrated as releasing pent-up anticipation from fans who had longed to see the band perform in their country.
