Two older mash ups back online:

The first one was mentioned in this wonderfully written and interesting article on Bootleg Mixes on Pitchforkmedia:
“Puritan Blister #7
The Psychopathology of Everyday Mash-Ups
Story by William Bowers”

“i wish i knew how it feels to talk loud and clear“
OMD: Talking Loud And Clear
Nina Simone: I Wish I Knew How It Feels To Be Free
März: Everybody Had A Hard Year
+ some Dead Prez & X-Ray Spex

and

“nanananananaaa – wanna be the man with the child in her eyes“
Placebo: I Do
(IMO this is one of the best songs they’ve ever written – a perfect short indiepop smasher with beautiful lyrics like “i wanna take a bath with you / wash the chaos from my skin” vs Kate Bush: The Man With The Child In His Eyes
(Nice news: I read that she finished recording a new album.)
vs Ce’Cile & General Degree: nanananana
(Taken from a compilation called “Two Culture Clash” (2004, Wall Of Sound), it also has nice tracks by Ms. Thing and Tanya Stephens.)
