I don't know how the survey is going or even if any of us have participated in it.
However I do know that this thread has taken off.
In regards to the original question, yes. I think a home studio is capable of producing an "authentic" rock recording.
Its all in the approach.
Most young rock bands have always started out at home. In someone's garage.
You got your songs, sound and chops down in someone's garage. Usually it was at the drummer's house because his parents and neighbors had a tolerance for noise.
However all good things come to an end and at some point you got kicked out and got your first taste of "pay to play"....... the rehearsal studio.
Anyway, those first adventures in the garages were quite authentic, and quite rock and roll.
3 or 4 guys or girls in one room rocking out.
If you were any good or not is a different issue.
Fast forward to today.
Never before has the technology been so abundant and inexpensive, as well as easy to get, as now.
Hell, you dont even have to leave your house. You research, talk about and learn what gear you need on the net. And when you are ready to purchase, you just click a button. Bam! Less than a week later gear shows up at your door.
Life made easy. You couldn't do that in the 60s, 70s, 80s, or even the 90s.
So today the technology is available to record authentic rock and roll.
But technology is a double edged sword.
It has also created a slew of one man bands with fake sounds, fake amps, fake vocals, etc.
Now dont get me wrong, these synthetic computer generated sounds can be quite realistic and be used very well.
The problem lies in the lack of a band.
instead of 3 or 4 live human beings interacting and creating music on real time, you now have quite a few "lone wolf" artists.
Some can do it, but most can't. Not all of us are on a level of Todd Rundgren.
Very few people can do it all themselves, and do it well.
In a band, with the interaction, you are forced to improve. There is always the drummer or singer to tell you your solo sucked. It works in the positive as well.
Besides, with a band, sooner or later you gigged. You can't really get good without gigging. Its a whole different world being up on stage in front of real people.
So with home recording having become so easy to do, almost anyone with some musical skill can do it.
So you get a lot of pure shit. The guy is trying to wear too many hats, and trying to do things he or she isn't good at.
One may be a great guitar player but a horrible writer. And many variations of that theme.
I have heard a lot of great stuff come from a one man writing, production performance team, but it is not common.
The best "authentic" rock and roll comes from a band. Real players with real instruments, recording real songs.
And yes, it can be done in a home studio. You just have to do it right.
Edit:
But then again, today you can collaborate with people you've never met, and may never meet in person.
It's a fucking brave new world!
