Psí vojáci (Dog Soldiers) was a Czech underground band from Prague, active between the years 1979 - 2011 and again from 2012 until 2013. Its frontman was a singer, piano player, composer and songwriter Filip Topol, son of the playwright Josef Topol and brother of the writer Jáchym Topol. He formed the band in 1979 along with his elementary school classmates – drummer David Skála and bass guitar player Jan Hazuka.

They were named after a military society of the Cheyenne Indians – Dog soldiers – which appeared in Thomas Berger’s novel Little Big Man. The roots of their music are in the world underground art, but there is also a strong influence of composers from the second half of the 18th century. On occasion, Filip Topol also performed solo on the piano and played songs from his solo albums, which were his inner confessions.
