David Castillo mixes "Slave" (Live at Rockefeller Music Hall) by Leprous and "Sorceress" (Live at Red Rocks Ampitheater) by Opeth

Mixed by David Castillo (not just the namesake of the song, but the sonic architect behind key Opeth releases), this session reveals intricate decisions made under the pressure of a live environment. Known for his work at Studio Gröndahl and his production credits with Katatonia, Bloodbath, and of course Opeth, Castillo’s work focuses heavily on authentic depth, tonal layering, and naturalistic yet impactful dynamics.

This multitrack session includes the full scope of a dense five-piece band operating at peak musicianship: richly textured guitar work, fluid tempo shifts, intense vocal harmonies, all wrapped in a nuanced live drum performance with zero click-track safety net. It’s an advanced blueprint for processing live cabs, rounding out overhead-heavy kit elements for punch and definition, dialing in DI-to-amp blend choices, and sculpting space for interleaving clean and saturated guitar layers without crowding the mix.
