Yes, there is some real talent on YouTube. I love this duo. They have a house full of instruments, some real good audio equipment, a great ear for quirky arrangements and the girl can really sing.
Some of their tunes are a little annoying, but its hard to beat this amazing harmonizing chord progression for
Favorite Things, partly done in 5/4.
Then this old
Nat King Cole Tune. Simply sublime.
And
Mr. Sandman by the Chordettes.
This is all multitracking by the same two or three people.
