The band came into existence in 1998 and has been continually developing a sound that has no equivalent in the world. The creators of the band, Kiril Georgiev and Zlatomir Valchev, were inspired by J.R.R. Tolkien's books and through his works came the name of the group. Lot Lorien's compositions, both the original music and interpretations of some traditional songs, combine elements from Bulgarian, Balkan and world folklore, jazz and progressive rock. The sound is further enhanced by the use of standard and non-standard instrumentation, such as acoustic guitar, bass, acordion, female vocal, keyboards, drums, percussion, glockenspiel, tapan, djembe, darbouka and others. The band has performed many concerts and festivals around the world in such locales as Bulgaria, Italy, the Russian Federation, Pakistan, Turkey, Poland, Slovenia, Finland, Cyprus, the Czech Republic, Romania, South Korea, Serbia, the Republic of Macedonia and Croatia.
