How does amplified progressive rock sound in a concert hall associated with classical music? Herwin Gunawan shares his listening experience at Laeiszhalle Hamburg through this recording of Ian Anderson and Jethro Tull performing “Locomotive Breath” on 13 October 2022.

Recorded on an iPhone 12 Pro Max from a position directly behind the sound engineer and assistant, the video captures a moment from the concert and provides context for Herwin’s acoustic observations. In his account of the performance, he describes the instruments as generally well balanced, while the acoustic drums sounded less distinct—a listening impression he associated with reflections within the hall.

The experience offers a starting point for considering the relationship between room acoustics, amplified sound, musical character, and audience perception. It also highlights the value of listening to a venue during an actual performance, where the music and the room are experienced together.

This video documents a personal listening experience. The phone recording provides an impression of the performance; it is not a calibrated acoustic measurement or a complete reproduction of the sound heard in the hall.

Part of the Herwin Gunawan Work field observation video library, this entry connects live music with his continuing exploration of architectural acoustics and human sensory experience.
