Yuck - Get Away
Now this is Break My Body by The Pixies off of Surfer Rosa (fav album evrrrrr).
The Pixies - Break My Body
Darn close huh? Now here's another song by Yuck titled Operation.
Yuck - Operation
From this song there's the melody of Teenage Riot from Sonic Youth. The opening to this song (serious nerd time) is a riff from the middle of the guitar solo in Sonic Youth's track Washing Machine.
Sonic Youth - Washing Machine (Start at 5:05)
Sonic Youth - Teenage Riot (Start at 1:50)
The last track that I can point out off the top of my head by Yuck is Stutter. I hear All Apologies by Nirvana.
Yuck - Stutter
Nirvana - All Apologies
Despite Yuck's songwriting tactics, I still think their a cool band. I do like the whole post-grunge sound they have and they CAN write songs on their own. It's just disappointing that some people (kids) are gonna hear Yuck and have no idea where all of these awesome riffs and melodies actually came from. Bummer. Sucks to be them.
