В те времена, когда каждый уважающий себя представитель культуры хип-хопа в России обязан был иметь в гардеробе трубы, и частенько в драке отстаивал свое право на «самоопределение», хип-хоп артистам было тяжело привлечь к себе внимание. Не было ни социальных сетей, ни Apple Music и SoundCloud. Но культура развивалась и должна была открывать двери для молодых талантов. И русский рэп пошел по стопам бардовской песни.
Какой формат помог открыть новых исполнителей для всех любителей жанра? Он появился, в первую очередь, благодаря Владу Валову, известному также как Мастер Шефф.
В народе укоренился афоризм: «не прошел ____, не видел жизни».

Что это был за формат?
Это ежегодное мероприятие проходит до сих пор, но уже не пользуется такой популярностью. Его прошли Каста, Смоки Мо и другие заметные люди субкультуры.
