Xenochrony is a studio-based musical technique developed at an unknown date, but possibly as early as the early 1960s, by Frank Zappa, who used it on several albums. Xenochrony is executed by extracting a guitar solo or other musical part from its original context and placing it into a completely different song, in order to create an unexpected but pleasing effect. He said that this was the only way to achieve some rhythms.
The word derives from the Greek words ξένος (xenos), strange or alien, and χρόνος (chronos), time.
One of the most prominent examples of xenochrony can be found on Zappa's rock opera Joe's Garage (1979), on which the guitar solos are all xenochronous (with the exceptions of "Watermelon In Easter Hay" and "Crew Slut").
In the words of Zappa himself:

When friends come for Saturday night
It's nice to make up some Sangria wine
It's organic and it comes from the vine
It's also legal and it gets you so high
Yeah I love that Sangria wine
Love to drink it with old friends of mine
Yeah I love to get drunk with old friends of mine
When we're drinkin' that old Sangria wine
CHORUS:
Whoa oh oh Woah oh oh I love Sangria wine
Whoa oh oh Woah oh oh I love Sangria wine
Start with some wine
Get some apples and brandy and sugar just fine
Old friends always show up on time
That's why you add Sparkling Burgandy wine
I love old Sangria wine
When I drink it with old friends of mine
Yeah I love to drink with old friends of mine
When we get drunk on that Sangria wine
CHORUS
In Texas on a Saturday night
Everclear is added to the wine sometimes
Some nachos, burritos and tacos
Who knows how it usually goes, it goes
CHORUS
Yeah I love that Sangria wine
Just like I love old friends of mine
They tell the truth when they're mixed with the wine
That's why I blend in the lemons and limes
And I love that Sangria wine
Love to drink it with old friends of mine
Yeah I love to drink with friends of mine
