The debut that made the band's name: eight Metallica songs arranged for four cellos and nothing else, from "Enter Sandman" to "Master of Puppets".

The second cello set widens the range to Sepultura, Faith No More and Pantera and slips in the first original pieces alongside the covers.

The turning point where original compositions take over from covers, marking the shift from a Metallica tribute to a band with its own voice.

Drums enter the picture for the first time, pushing the cellos toward a heavier, fuller metal sound with guest players on board.

The self-titled album balances instrumentals with vocal tracks, inviting guest singers like Ville Valo and Lauri Ylönen.

A guest-heavy record carried by the single "I'm Not Jesus" with Corey Taylor, pairing cellos with rock and metal vocalists.

The seventh studio album mixes instrumental force with guest vocals and even a drum turn from Dave Lombardo of Slayer.

For the first time the band works with a permanent lead singer, Franky Perez, leaning fully into song form.

A return to a fully instrumental album, its title nodding to the smallest unit of life and to a fresh start for the trio of cellists.

A sequel to the debut nearly thirty years on, revisiting Metallica for four cellos with the polish of a seasoned band.
