advertising on twitter and instagram account for promotion is of course cool, but I think it's too long a way. I would advise you to just contact the agency amv near me. They helped my friend when he released his first album with advertising, so I know for sure that they will be able to help you with this. The main thing is not to make big mistakes at the initial stage of promoting your product, since the audience will remember you by the first steps in this industry, and it will be very difficult to change the first impression. Most often, this is the problem of young artists, so I advise you to simply turn to professionals in your field.
