Jack White's LAZARETTO ULTRA LP & VINYL
Over the past 5 years Jack & Third Man Records have brought to life many ideas that were new to the century-old vinyl format. Today they unveil the Lazaretto ULTRA LP:
- 180 gram vinyl
- 2 vinyl-only hidden tracks hidden beneath the center labels
- 1 hidden track plays at 78 RPM, one plays at 45 RPM, making this a 3-speed record
- Side A plays from the outside in
- Dual-groove technology: plays an electric or acoustic intro for “Just One Drink” depending on where needle is dropped. The grooves meet for the body of the song.
- Matte finish on Side B, giving the appearance of an un-played 78 RPM record
- Both sides end with locked grooves
- Vinyl pressed in seldom-used flat-edged format
- Dead wax area on Side A contains a hand-etched hologram by Tristan Duke of Infinity Light Science, the first of its kind on a vinyl record
- Absolutely zero compression used during recording, mixing and mastering
- Different running order from the CD/digital version
- LP utilizes some mixes different from those used on CD and digital version
Watch Jack and Ben Blackwell discuss and demonstrate the ULTRA LP features below.
