The project consists of combining live music, interviews, and audiovisual content, broadcast live for 12 hours via Ràdio 4 and RTVEPLAY. There will be 12 hours of live content on radio and global streaming, which could achieve a Guinness World Record, as this has never been done with Catalan rumba. Thus, for 12 consecutive hours, a series of live concerts will be performed by the participating artists (at least 35 individual artists and groups), interspersed with interviews with the artists and representatives of Catalan rumba.
