A music recording session typically lasts all day and involves many people serving different roles like artists, sound engineers, producers, and instrumentalists. Equipment like microphones, instruments, and mixing boards are also essential. An A&R department at a record label is responsible for scouting new talent by attending shows and searching social media. Once signed, they oversee an artist's development by choosing producers, studios, and determining which songs will make the most money. In the past, record labels provided major support like funding, facilities, distribution, and promotion to signed artists in exchange for a large cut of profits once an initial advance was paid back.
