The complete six-stage album series Everywhere at the End of Time by The Caretaker, about 6.5 hours of music that depicts the progression of dementia through distorted, decaying old ballroom recordings.

debuglive makes a 1990-style dance track on an Amiga 500 with a Stereo Master sampler and cheap secondhand records, showing how sampling and trackers worked within tight memory limits.

Ryuichi Sakamoto's piece Blu, performed by the Tokyo Philharmonic Orchestra. It was written to commemorate the 50th anniversary of the Aoyama clothing company.

Rick Hartley gives a roughly two-hour live training on proper grounding in PCB design. He explains how energy actually flows in the space between conductors, and how that governs noise, EMI, return paths and signal reflections.
