Mixing Opeth’s ‘Sorceress’ Live: Tackling Wind, Bleed, and No Reverb

Let’s be honest, Opeth’s Live at Red Rocks is one of the best-sounding concert albums ever made. Originally recorded by the legendary David Castillo, some of the mixes on this record arguably rival—or even surpass—the studio versions. It’s the pinnacle of live recording, capturing a truly magical performance without any studio touch-ups or overdubs. This is 100% raw, what-you-see-is-what-you-get Opeth.

But getting it to sound that good wasn’t simple. Mixing a show recorded at an outdoor amphitheater like Red Rocks comes with a bizarre set of challenges you’d never encounter in the studio. We’re going to unbox the raw multi-tracks from the song “Sorceress” to show you what it takes to mix a live metal masterpiece, complete with wind, crowd chatter, and a total lack of natural reverb.

The Foundation: A Flawless Live Performance

Before we even touch a fader, let’s get one thing straight: this band is ridiculously good. You can pull up the raw tracks, do some basic leveling, and it already sounds incredible. This isn’t one of those “fix it in the mix” situations.

The first time you hear the raw drums, you can feel the pocket that their drummer, Martin Axenrot, is famous for. It’s a groove you can’t edit in; it’s either there or it isn’t. From the tightness of the guitars to the precision of the keyboards, the performance itself is the solid ground we build the mix on. A great mix starts with a great source, and these tracks are as good as it gets.

Mixing Challenge #1: Creating Ambience from Nothing

When you imagine hitting a snare drum in a massive outdoor space like Red Rocks, you might picture a huge, epic sound. The reality is the opposite. With no walls for sound to bounce off of, you just get… air. The raw tracks, especially the drums, are incredibly dry.

This is the first major hurdle: you must create all the ambience yourself.

How to Build Your Own Space

For those who have mixed drums recorded in a small, dead-sounding room, some of the same techniques apply here. You’re essentially building a virtual room from scratch.

• Drums: Start with a short, tight plate reverb on the snare to give it some crack and body. Use a plugin like Valhalla Plate or the classic Lexicon 224 emulation. For the overall drum kit, send the overheads and room mics (or in this case, audience mics) to a larger hall or room reverb to create a sense of cohesive space.
• Guitars & Vocals: These will also need their own ambience. Try subtle delays to create depth without washing them out, followed by a medium hall or chamber reverb to place them in the same “room” as the drums. The key is to make it sound natural, like the band is playing in a real environment, not just a collection of dry tracks with effects slapped on.

Mixing Challenge #2: Taming Massive Track Bleed

In a live setting, everything bleeds into everything. The PA system, the wedge monitors, the sheer volume of the amps on stage—it all gets captured by every single microphone. The “Sorceress” tracks are a masterclass in bleed. The vocal mics are full of cymbals and guitars, and the drum overheads are practically a full band mix on their own.

You can’t escape it, so you have to learn to manage it.

Strategies for Managing Bleed

Your first instinct might be to eliminate all of it, but that would strip the mix of its live energy. The goal is control, not total annihilation.

• Gates and Expanders: For transient-heavy sources like kick, snare, and toms, a gate is your best friend. Use a plugin like FabFilter Pro-G or the gate on an SSL-style channel strip to clean up the space between hits. This prevents cymbal wash from turning your tom fills into a mushy mess. Smart use of dynamic control is key.
• Phase Alignment: Sometimes, bleed can work for you. The snare bleed in the overheads, for example, can add to the overall snare sound if it’s in phase with the close mic. Use a tool like Sound Radix Auto-Align to check and correct the phase relationship between your close mics and your overheads/room mics. You might find it thickens things up considerably.
• Embrace It (A Little): Accept that some bleed is part of the vibe. The trick is using it to your advantage to make the mix feel cohesive and powerful, rather than letting it take over and cloud the clarity.

Mixing Challenge #3: Unconventional Problems: Wind and Crowd Chatter

Here’s where things get really weird. Because Red Rocks is essentially carved into a mountain, you have to deal with an element you’d never find in a studio: wind.

On top of that, the front-of-house mics were placed low enough that they didn’t just capture the roar of the crowd—they captured individual conversations.

Dealing with Wind Noise

In the overheads, you can hear a subtle (and sometimes not-so-subtle) high-pitched whistle. It’s the sound of wind whipping past the microphones. Original mixer David Castillo even mentioned having to choose which overhead mic to use based on which one had less wind at any given moment.

To fix this, you’ll need some surgical EQ. Use a parametric EQ with a narrow Q setting, like the FabFilter Pro-Q 3, to sweep the high frequencies, find the exact pitch of the whistle, and notch it out. A high-pass filter can also help remove any low-end rumble caused by wind hitting the mic diaphragm.

Handling Individual Conversations

While you want the sound of the audience in a live mix, you probably don’t want to hear two guys discussing what they’re getting to eat after the show. When you start adding compression and bringing up the details, these conversations can become distractingly audible.

This is a job for automation. Go through the FOH/audience tracks and manually dip the volume with fader automation during quiet parts or whenever a specific voice pops out. For really problematic spots, you could even use a spectral editor like iZotope RX to surgically remove the offending chatter without affecting the overall crowd noise.

The Genius in the Arrangement: Protecting the Voice

One of the coolest insights from these tracks has nothing to do with processing. It’s about the band’s arrangement. To get through a two-hour show, Mikael Åkerfeldt needs to preserve his voice. Throughout the song, you can hear vocal duties being intelligently traded between Mikael and other members, like the keyboardist and guitarist.

It’s a crafty, professional move that ensures Mikael has full power when he needs it most. It demonstrates a level of forethought that separates the pros from the amateurs.
