Definition and Duties of a Manager for Soloists and Bands
It's rare for an artist to also have a head for business, which is why most musicians(whether they perform solo or work in a band) retain a manager. In essence, managers are in charge of running all aspects of the business side of the artist's or the band's career. This allows the talent to focus entirely on creating the music. The role of a manager varies. A manager responsible for an unsigned band or musician, or, if they are signed to a small label (such as 4AD, Matador Records or XL) often wears multiple hats.
This kind of manager serves as a promoter, agent, accountant, or any other kind of professional the artist needs to perform and have a viable career. A manager working for an artist signed to a large label (such as Warner Music Group, EMI or Sony Music) functions in more of a managerial capacity and supervisors the other people employed by the musician(s). These managers have oversight and ensure that essentials such as advertising and PR campaigns are running smoothly, that tours are being booked and that artists are being paid.
