Tichá dohoda was a Czechalternative rock band (1986–1999). They were pioneers of Czech indie scene in the '90s headed by songwriter, guitarist and producer Dan Šustr and with the frontwoman and singer Blanka Šrůmová. Their stubbornness, attitudes and opinions on sex and drugs and rock n roll labelled the band difficult for a Czech pop establishment in the late nineties. Despite their eight local hits, several local Grammy-awards nominations, creation of their own style called "underpop" (2nd album called "Underpop“ released 1992) and the first Czech unplugged record ("UnplugGag“ 1994) the band did not seem to fit in the marketing plans of majors and the last official new album was released by Sony Music in 1998 (Válcovna vkusu s.r.o. – Public Image Mill Plant ltd.). The band members reunited in 2006 under the name 2Wings.
