This one's for the guitarists.
I think most people who learn guitar these days check out videos on YouTube. And if you do, you've probably come across Marty Schwartz, who runs Guitar Jamz and has a very popular lesson channel. In fact, his Blaze of Glory tutorial was shared by Bon Jovi's Facebook page last year.

Anyway, Phil X recently joined Marty for a rock soloing lesson using the pentatonic scale.

Phil also demos vintage guitars on the Fretted Americana channel and is pretty amusing while doing so.
