Apocalyptica is a symphonic metal band with 3 cellists as the core of all their work. Sometimes they also have drums, electric guitar, or vocals. It varies from album to album and song to song.
There’s a great orchestral version of “Animals” by Architects if metal works for you.
Going back to the 90’s Metallica did a concert and live album with the San Francisco Symphony.
It’s not exactly what you asked for, but Sean Townsend does great piano covers of rock/metal, especially Killswitch Engage. His music is very relaxing to listen to. Most of his material is on YouTube, which is a shame because I would buy his music if it were for sale somewhere.
I’ve been curious about this too, but haven’t been able to find anything that puts a real price (including future profit margin) on GenAI. For example, having a chat conversation with a customer service agent in India might cost about $2-3. Is a GenAI bot truly cheaper than that once you factor in the energy & water costs, hardware, training, profits, etc.? It might be, but I’m skeptical.
