"Things You Wouldn't Know If We Didn't Blog Intermittently."
Epic, very impressive
The mashed-up recordings were not in the same key, so one had to be sped up and the other slowed down. The "Stayin' Alive" recording is in F minor. For "Another Brick" it's a little harder to say; I found a recording in E-flat minor but other sources say it's in D minor. This mashup ends up somewhere between E and F, and I imagine someone with perfect pitch would cringe.
