Below is a challenge to musicians everywhere to produce a pure wall-of-sound record based on the following rules:
1. Recording shall take place in a kind of environment familiar to listeners and musicians. For instance, houses, offices, markets, gyms and malls. An effort should be made not to record in sonically-treated spaces such as echo chambers and studios with foam-padded walls.
2. Upon public release, the recording shall include documentation to show where the recording was made and where all the musicians sat or stood.
3. Only one mic shall be used to record the master. Additional mics are permitted only for the purpose of monitoring.
4. Monitor speakers are not allowed. Musicians being recorded may only use headphones for the purpose of hearing themselves and the other musicians clearly.
5. No instrument shall be amplified, except for instruments that require amplification, such as the electric guitar and keyboard. These instruments must be connected to their own amps (one amp per instrument) and must not be connected directly into the sound board. The volume on the amps will be set to the minimum required to obtain the desired tone.
6. No singer shall be individually mic'd, except for monitoring reasons. All singers (along with everything else) will be recorded through the one master mic. No pitch correction or special effect will be added to the vocals.
7. Any equalization adjustments shall be done on the actual instruments and amplifiers, not on the soundboard. Unamplified musicians can move around the room to achieve a desired EQ in the final mix.
8. The use of screens to reduce volume is discouraged. Volume reduction should be done by moving the musicians farther from the master mic.
9. If a singer is playing an unamplified instrument such as the piano or acoustic guitar, and the master mic cannot be placed in a way that properly balances the vocals and instrument, it is up to the singer to maintain a proper volume of the instrument by playing technique alone.
10. If a singer is playing an amplified instrument, the amplifier will be moved away from the singer as appropriate.
In researching this section, I discovered that Scottish pop band Aberfeldy has already done this. (http://www.soundonsound.com/sos/sep04/articles/aberfeldy.htm). But I'm still interested to see if it can be done on a massive scale in order to maximize the depth of the record.
