Raivis began his musical journey in Riga, Latvia, where he was born. He sang in a boys' choir during his primary and secondary school years, which fostered his passion for music. At the age of 12, he was captivated by the sound of a symphony orchestra at an oratorio concert, prompting him to apply to music school. Raivis played the French horn for six years before switching to the double bass at the age of 18. He won first prizes in national youth competitions for both instruments and developed an interest in composition under the mentorship of renowned composer Pēteris Vasks.
