Ruja is an iconic Estonian rock band, known for their profound influence on the development of rock music in Estonia during the Soviet era. Their music, characterized by poetic lyrics and progressive rock influences, has left an indelible mark on Estonian culture and continues to be celebrated decades after their prime.

The band was formed in 1971 in Tallinn by keyboardist Rein Rannap and vocalist Urmas Alender. Throughout their career, they weathered political challenges and lineup changes but remained at the forefront of the Estonian music scene. The titles of their releases often reflect a deep engagement with literature and national identity, such as "Kirjanduslik" (Literary) and "Rahvuslik Rokk" (National Rock), showcasing their commitment to intertwining music with intellectual and cultural exploration. Ruja's most revered songs, encompassed in albums like "Esimene" (First) and "Pop RUJA," continue to resonate with Estonian listeners, evidencing the timeless quality of their artistry. The live compilations "Algu" and "Hiline" series capture the band's dynamic stage presence and the evolution of their sound across the years. Although Ruja disbanded in the late 1980s following the tragic death of their charismatic lead singer Urmas Alender in the MS Estonia disaster in 1994, their legacy persists as a cornerstone of Estonia's musical heritage.
