Music

If you like metal there's Septicflesh, Dimmu Borgir, and Flesgod Apocalypse

Hybrid. They are electronic musicians who record with live orchestras. Very nice music. The album, Morning Sci-fi, is a brilliant achievement.

I'd recommend some post-rock stuff too. Sigur Ros with symphonic orchestra is amazing.

Or things like Neil on impression, Nice wings Icarus, some Mono and such.

Here's Tiesto's Adagio for Strings with a live orchestra

Not exactly what you're asking for, maybe, but Brass Against is excellent. Their rendition of Hey Man Nice Shot is incredible.

Edit: I also just remembered Mr. B The Gentleman Rhymer, if you need a dose of chaphop.

Not quite like the albums you mentioned, but here's some stuff that all incorporates some classical instruments with modern rock instruments

• Laideronnette or zatracenie by matryoshka - maybe the most like what you mentioned, ambient-ish with strings and piano
• イリヤ (- il y a -) by 夢中夢 (mutyumu) - maybe a bit avant-garde, but makes heavy use of strings and piano
• Enjoy Eternal Bliss by Yndi Halda - post-rock with strings
• ONDA by JAMBINAI - Korean post-rock that mixes traditional Korean instruments with modern rock instruments

Lots of jazz and rock music meets these criteria

Symphonic metal is a huge and diverse genre! Nightwish, Epica, Within Temptation, Kamelot are good places to start.

Wow so many suggestions, I did not expect that. You all are amazing, what a great community! Thanks, I know what I'll be doing tomorrow 🎧

Portishead do this so well

Very closely adjacent to this:

Eric Whitacre's Virtual Choir

Definitely check out the Flobots, they're most well known for the song "Handlebars" (I can ride my bike with no handlebars) -- but they are so much more than that song. They are comprised of 2 MC's, a violinist, a bassist and drummer, but they often have a lot of orchestral instruments featured in various songs.

Every album is just so good, highly recommend.

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.

You just reminded me of Red Light in My Eyes from Children of Bodom. There's an interpolation of J. S. Bach piece, Invention No. 13 (BWV 784)! It has been a while since I have listened to it. haha

• Igorrr. It's very out there but if you don't mind that, it's so so amazing. It's mainly electronic music (mostly breakcore?) + classical instruments + extreme metal and more. Here's a good example. It's off of their amazing album Hallelujah, which I really recommend.
• Venetian Snares. A more laid-back version of Igorrr. It's mostly electronic music and classical music. Here's Hajnal, off of their album Rossz Csillag Alatt Született.

I feel like I have to tell you about the fabulous, most groovy... Bellbottoms (by The Jon Spencer Blues Explosion).

Unfortunately it's just less than 2 minutes on the intro of one song. I wish they had done some more like it, because it's a great combination in my opinion.

Maybe electroswing? I found a Caravan Palace mix you could try, if that’s what you’re looking for there’s also Caro Emerald and ProleteR

Johann Sebastian Bach combined with 90s hip hop beats:
