Björk

Björk's preferred studio mic. Her vocal on "Unravel" was recorded with an SM58, according to a Waves webinar with producer & co-writer Guy Sigsworth (at 37:45):

I have even made really popular records with SM58s. Björk's vocals on "Unravel" are SM58, and they were just great performances, didn't mind about the mic.

In this October 13, 2011 SonicScoop interview with mix engineer Damian Taylor, he mentions that Björk also used an SM58 for Volta and Biophilia.

One thing that remains consistent, however, was Björk’s method of recording vocal takes. Taylor says she’s not one to stand perfectly still with headphones on. Instead, she’s favored a handheld Shure SM58 for years, and she still tracks all of her vocals while listening out-loud on studio monitors.

When Taylor brought her a Neumann KMS 150 handheld condenser to try, he says that she “sang all of two syllables into it” before handing it back for the 58.

On a few songs that needed extra sensitivity and detail, Björk sang into Martin Kantola and Bruce Swedien designed NU-47, a classic redesign of the U47 with striking wooden body. Otherwise the chain was simple: The Shure SM58 into a preamp with little or no compression.

“When I’m recording Björk, I try to compress as little as possible. Basically never. I do have a little something there on the chain just as a safety net, but basically I ride her performances the whole way in. Her dynamic range is just insane. Fortunately, I’ve gotten to know her pretty well, so I can start to feel when she’s about to take a breath and ride my output gain knob. This way, we’re not getting a squished sound going in, but we’re still getting consistent levels.”

(...) Originally, Taylor plugged the SM58 into a Neve 1084, with a Urei 1176 as his safety net. “That worked really well for Volta, where the voice had a more rock and roll sound.” But for this record, he realized the voice “would be a more delicate kind of thing”, and he came to prefer Björk’s Focusrite ISA 430 Producer Pack, while largely avoiding its built-in EQ and compression.

Used for vocals on Homogenic, as stated by producer Markus Dravs in this October 6, 2008 Audio Pro International interview (as transcribed on the Brian Eno fansite Brian Eno is MORE DARK THAN SHARK).

Dravs explains that her vocals are often recorded in a very simple fashion. "A lot of times, Björk would listen to an almost finished mix and then pick-up a Shure SM57 mic in the control-room, with the speakers on (with a bit of Urei compression on) and re-sing the lead vocal in order to adjust her singing dynamic to what she's hearing at that point and then lay down a blinding performance, as she has got such great mic technique," Dravs reveals.

Much of the writing and recording of Vulnicura took place at Björk’s New York home, where she has the ultimate 21st Century studio. The total music–tech content consists of an Avid Pro Tools HD Native Thunderbolt system, Genelec 1032 monitors (“I like them a lot, they sound very creamy. But they can be deceptive, because everything sounds good in them. So you have to be a little careful.”), an M–Audio controller, a Telefunken ELAM 251 microphone and Neve 1081 mic preamp.

Used for Biophilia "[o]n a few songs that needed extra sensitivity and detail," as stated by mix engineer Damian Taylor in this October 13, 2011 SonicScoop interview.

Producer Bruce Swedien confirms Björk's use of the NU-47 on this page of the microphone's official website.

Of course, it's a fantastic vocal microphone. There have been very few NU-47's made. One was made for Icelandic singer Björk, who absolutely loves the sound of this incredible new microphone. She told us that, "It captures both the small and the big sounds that I make!"
