...and only just.
Welcome to HR.
Thanks. I am not a producer or recording guru. I am a singer and guitar player trying to record myself at home with hit or miss results. Another book I was reading mentioned this website and I thought I would have a look.
Anyway, so, yeah, like the other guy mentioned AC/DC's "Flick of the Switch" tanked kind of hard and I might agree that it is because Mutt was not producing. I remember correctly, Mutt did produce "Back in Black," their biggest selling album and one of the biggest selling rock albums of all time, even competing with Guns and Roses "Appetite for Destruction" for total units sold. I read histories and memoirs but I cannot remember why they chose to self-produce FotS except that the Young brothers do like to control things. For a while, they would not let Brian write any lyrics. Most of the songs during that era were written soley by Malcolm.
Here is the problem with self-production, which I hope we can overcome, somewhat. And I know this especially as a singer. A singer cannot hear himself as others hear him. Not just because of bone conduction in the body. But mentally. Even in recording playback, it is nigh unto impossible to be objective. Same, sometimes, with a band self-producing, with one exception, Jimmy Page. With the exception of Led Zeppelin I, Jimmy took over ever increasing production duties on the albums, with good results, I think. Houses of the Holy is such a finer production than the first album, partly due to technology and certainly due to having a good ear.
Because that is what makes a good producer. I honestly believe that and not just because I have read it. A good producer has ears, not millions of dollars in gear. I have good sounding recordings with a guitar that I bought at a flea market for $40 in Kleburg, Texas (east and a little south of Dallas.) So, just as a decent guitar player can make a cheap guitar sound good, a producer can make something good with limited time and equipment.
Talent to play and sing well is not the same talent as listening to it and balancing it. It really is a skill. As is mastering. Which a person can learn all of this but having fresh ears help.
