A session musician is a professional musician hired to perform in recording sessions or live performances. They are often skilled in playing multiple instruments and can adapt to various musical styles. Session musicians work with artists, producers, and bands to create high-quality recordings or enhance live shows. These musicians typically do not belong to a specific band or group; instead, they are freelancers who collaborate with different clients. Their versatility and expertise make them valuable in the music industry, contributing to projects across genres, from pop to jazz to classical, often without being credited as the main artist.
