There is music so unique, so colorful, and so potentially challenging for the casual listener that words like "pretty" or "entertaining" go flying out the window. Such is the case with pianist Pierre-Laurent Aimard's mind-boggling recording of Olivier Messiaen's (1908–1992) Catalogue d'Oiseaux. Anything but background music for a relaxed evening by the fire or in the hot tub, the Catalogue consists of 13 extended odes for solo piano, each of which was inspired by a different bird species. Recorded by Pentatone in 24/96 hi-rez stereo and surround in the famous Saal 1, Funkhaus, Nalepastrasse, Berlin, and issued as a three-disc SACD set (PTC 5186 670), the box includes a bonus DVD on which Aimard, a professor at the Hochschule Köln, discusses the pieces at length and offers insights into Messiaen the man and composer.

Brooklyn, 1979: Fridays were fierce. After a week of doing construction, I would gobble Wild Turkey at the Spring Lounge, then fall asleep on the F train with a fold of cash and a Sony Walkman stuffed in a chest pocket of my paint-spattered Belstaff Trialmaster jacket. Usually I missed my York Street stop by only a few stations, but occasionally I'd wake up at sunrise on Saturday at the last stop: Coney Island. I didn't mind. It was restorative to shuffle the deserted boardwalk, listening to the Ramones' Road to Ruin or Television's Marquee Moon.

In the March 2018 issue, Art Dudley admired the sound quality of Ayre Acoustics' KX-5 Twenty preamplifier, but didn't love some of its operational aspects. I've staged this Follow-Up as a putative face-off between the Ayre and my current reference preamplifier, the PS Audio BHK Signature, which I reviewed in the June 2017 issue.

Wilson Audio founder, Dave Wilson, 73, died of metastatic bone cancer on Saturday evening, May 26. Dave was receiving hospice care at his Utah home, and took his leave with his beloved wife and partner, Sheryl Lee Wilson, and other family members at his side.

Dave's exit came after he had overseen the 2006 expansion of Wilson Audio's factory in Provo, Utah by over 60%; announced, in November 2016, the succession of his son, Daryl Wilson (then 38) as CEO and President of Wilson Audio; and completed his magnum opus/ultimate statement, the limited edition WAMM Master Chronosonic loudspeaker ($685,000/pair). Secure in the knowledge that Daryl, who had already contributed to or taken over the design of at least 32 successful loudspeaker models, he was able to depart with a sense that his legacy as one of the great innovators in loudspeaker design will live on.
