Brown Grass: Gregory Porter carries his own song into Blue Note

One of ten originals on a Blue Note debut

“Brown Grass” begins with the songwriter as well as the singer. HFI’s production master credits Gregory Porter with both roles. Blue Note introduced Liquid Spirit as Porter’s debut for the label and described ten of its fourteen tracks as new originals based on personal experience; the label’s official track list places “Brown Grass” ninth.¹²

That provenance gives the listening a useful centre. Rather than treating the voice as an isolated demonstration, hear how Porter carries his own song: words, line and vocal presence belong to the same authored performance.¹²

HFI used the 96 kHz/24-bit Blue Note edition of Liquid Spirit released on 10 September 2013.

Keep the singer and songwriter together

On the first pass, stay with the whole performance. Follow the way each phrase completes its thought before looking for individual sounds. The point is not to turn a personal song into an equipment checklist, but to keep its language and musical motion connected.

Then listen again with attention moving outward from Porter’s voice. Notice when accompanying lines step forward, when they leave him room and how the space around the performers changes from phrase to phrase.

Six independent paths from the T1

The playback chain comprised CH Precision X1, T1, C10, L10 and M10 components with Göbel Divin Majestic loudspeakers.

CH Precision describes the T1 time reference as having six independent outputs. Each output has its own buffer and transformer coupling, and can be configured for a 10 MHz sine or square wave at 1 V or 500 mV.³

With that system context established, return to the music. Listen for whether the song remains easy to follow as attention shifts between Porter, the supporting players and the recorded space.³

A sweet-spot perspective from KD Sound

HFI recorded the session at KD Sound on 25 May 2025. A matched pair of DPA-4011 microphones fed a Zoom F8n Pro at 192 kHz/32-bit float.

A laser distance meter matched the microphones’ distances from the loudspeakers at the position where that pair most closely captured the sound heard at the sweet spot. That microphone-dependent position is not necessarily the physical listening seat.

Put on headphones and sit in the sweet spot. Let “Brown Grass” unfold once as Porter’s song, then return for the quieter handovers between voice, accompaniment and room.
