What could have been.
The video shows the process of how Metallica and Lady Gaga work on the song “Moth Into Flame”.
The video shows how they make their song sound with improvisation and experimentation to get better. Lady Gaga is seen playing her guitar and singing while Metallica is seen auditioning various drummers. They both work together to improvise in a way that sounds natural. This is unusual because most collaborations happen over email, phone or text where it is difficult for the artists to collaborate in person.
