Russian rock music often makes use of unconventional instruments along with the typical drums and electric guitars. Sounds within the rock genre can vary greatly from heavy, dark songs to lighter classic Russian rock. When compared with Western rock, lyrics tend to have a greater role in the rock of Russia. Impassioned delivery of lyrics has even occasionally replaced vocal melody. Well-known Russian rock artists include Zemfira, Billy's Band, Psoy Korolenko, Linda, Ska Jazz Review and Markscheider Kunst.
