Pedal Steel ...

The video could be better but the music, well, that's something else altogether.

Pedal Steel Guitars live. :)

Also, it is one of the most difficult-to-learn instruments in the world. Just setting up the pedals and levers requires an intense amount of foreknowledge. There are multiple standard tunings. Its strings usually run in a non-intuitive order. Playing it requires both hands, both feet and, occasionally, both knees. Sometimes there is one guitar neck full of strings, sometimes there are a few — each in its own tuning. Its mechanics have very little to do with guitar as most recognize the instrument, or even the open-tuned Hawaiian lap steel, from which the pedal steel evolved.

Here's a double-neck version.

Awesome to a fault.
