Rock legends Metallica are now holding forth in their first-ever internet class.

In their online course, offered through celeb-oriented learning company MasterClass, the group’s foursome — James Hetfield, Lars Ulrich, Kirk Hammett and Robert Trujillo — will reflect on the four decades of their partnership.

The course comprises 15 individual video lessons, spanning a total of 2 hours and 45 minutes. Metallica promises to give enrollees “a window into their journey to teach strategies for growing and staying together as a band,” according to MasterClass, as well as collaborating creatively and maintaining a “unique and intimate relationship with a loyal legion of fans.”

Metallica will unpack the principles that ensure longevity as a group by being effective communicators, and how to manage criticism, according to the MasterClass announcement. The online class will break down some of their greatest hits, including “Enter Sandman”‘ and “Master of Puppets,” and provide techniques for songwriting, taking members through the process of a song from its conception as a riff to the finished arrangement, complete with lyrics, solos and “moments of dynamic tension.”

“We have sustained our bond for more than 40 years because we’ve learned a lot about each other and ourselves over time,” Hetfield, lead vocalist, rhythm guitarist and cofounder of Metallica, said in a statement. “In our class we not only teach MasterClass members how we write songs and find inspiration for our music, but how the experiences we’ve had together have contributed to successful creative collaboration.”
