War Horse - Dartmoor, 1912 John Williams
Take a look at our incredible list of the most amazing, mind-blowing and insane classical music videos on the internet - includes heavy metal Vivaldi, the world's fastest pianist and a xylophone made out of a Japanese forest.
The man who can whistle the Queen of the Night
We are speechless. This man is Michael Barimo, and while at a party in 2011 (held by violinist Joshua Bell - how cool is that?) he got up to do his party piece, which happens to be WHISTLING the entire Queen of the Night aria from Mozart's The Magic Flute, otherwise known as one of the most difficult soprano arias in existence. And he nails it, obviously.
Fastest guitarist in the world?
Is it real? Is it fake? It doesn't matter - just listen to how insanely quick the notes fly past and how mesmerisingly quick this guy's fingers move. It's proved to be a viral hit, unsurprisingly.
Forest xylophone plays Bach
Why would anyone rig up a ludicrously elaborate wooden xylophone that plays 'Jesu, Joy of Man's Desiring' in a Japanese forest powered only by gravity and a wooden ball? It really doesn't matter. The results are amazing.
In which a stony-faced 14-year-old girl shreds like an 18th century Eddie Van Halen and takes Vivaldi's Four Seasons to totally righteous new places. Horns up!
Rollerblader plays Mozart on empty beer bottles
Take some rollerblades, some ski poles, a brewery's worth of empty beer bottles and Mozart's most famous symphony - what do you get? Brain-exploding video gold, that's what.
World's largest tuba
It's the world's largest tuba. A Jeremy Spake lookalike plays Flight Of The Bumblebee on it. You need to watch this video.
So many puns
The greatest selection of musical puns in history (Trombone Thugs 'n' Harmony, anyone?), and each one gets its own musical interpretation. Unrivalled levels of geekiness.
World's fastest pianist
Never has the concentration face of a young man in front of a piano been so intense. Somebody get that guy a wet flannel.
Bach floor piano
Sometimes, working in a toy shop gets a bit old. So to pass the time, these two geniuses (and, we suspect, fans of Tom Hanks' oeuvre) turn Bach's Toccata and Fugue in D minor into a frenetic foot work-out.
Rite of Spring visualisations
All the intertwining lines of Stravinsky's Rite Of Spring are laid out in graphical form. While that might not especially exciting, we defy you to keep your mouth closed when the textures go insane and the colours become a retina-battering blur at the six minute mark.
Pianist with no fingers
If ever you're doubting the power of the human spirit, this simple bit of Mozart's Rondo Alla Turca will sort you out immediately. 'Scuse us... something stuck in the eye...
Beethoven's 9th Flashmob
Flashmobs are surprisingly common these days, so it takes a lot for it to be properly mind-blowing - and this one really is. If you don't get goosebumps when the massed voices come in at the end, we're not friends any more.
