Garry Havrillay presents a quirky 4-part audio series about the humble vinyl LP, with geeky insights into artifacts of the medium;
• using the run-in and run-out grooves as creative space
• multiple spirals on the same side of a disc
• the impact on LP quality during the oil crises of the 1970s
• half-speed cutting for audiophiles, and
• the most challenging record ever made for any stylus & cartridge to navigate!
Part 1 explores the idea of using the run-out groove as creative space, and the crazy idea of having an "alternate program" by cutting multiple spirals on the same side of a record. (This part is a reworking of an original commission for ABC Radio National.)
In Part 2, Garry spins a disc with audio cut into the run-in as well as the run-out groove, explores the care needed to craft a perfect 1.8 second loop in the lock-groove, and the change in pitch when the tonearm swings from side-to-side (known as 'wow').
In Part 3, Garry explains why the audio must be severely equalized to reduce the bass and boost the treble before it's sent to the cutting lathe, and tries to play an audiophile record that recorded real cannons in a pre-CD era precision digital recording (pictured top).
In Part 4, Garry demonstrates the huge sonic benefits of cutting the record at half-speed, the consequences of recycling surplus LP records (!), and joins the ego trip with artists who looped applause at the end of their concert albums.
