seperate radio mixes - the scoop
I'm thinking most of you already know this - I hope I'm not being redundant, but I used to work in radio. - that there are some mixes that are tailored to Radio FORMATS!!! - For example, Goo Goo Dolls "Naked" was 95% distortion on the record, yet for the radio mix (what I'd call a CHR mix) it was about 40-50% distortion and 50% clean guitar mix - (John R. says they split his guitar signal and always kept one running thru
a roland jazz chorus just in case )
Most times, when you hear "Radio Mix" it means the song is cut shorter. There's a whole bridge/tangent in Third Eye Blind's "Semi-Charmed Life" that no one ever really hears unless they buy the record.
Depending on what the station sounds like, you'll also hear alternate mixes - which are usually shipped on the CD single (with intro, without intro, acoustic, crap like that - heavier drum mix - even a techno remix) - , but those are more format changes in instrumentation, not necessarily a compression change just because it's radio.
Another primo example. We got a copy of Seven Mary Three's "Cumbersome" (remember that one hit wonder?) and it had an acoustic version of the song, which essentially was the same song but the distorted track sounded like it had been stripped and run thru something like a Boss Acoustic Simulator pedal - exact same song and instruments and virtually the same riff , but they altered it for an acoustic mix. (In case your Top 40 station didn't like too much grunge)
And now I'm just a loser doing network support, but hey, at least I don't have to make the choice between tater-tots and rent.
