Ideally, LPs should be played with the pickup stylus remaining tangential (<I>ie</I>, at a 90&#176; angle) to the groove&#151;just as the lacquer from which the LP was ultimately stamped was cut in the first place. Over the years, many attempts have been made to accomplish this. Back in 1877, Thomas A. Edison's original machines tangentially tracked his cylinders, but Emil Berliner's invention of the flat disc put an end to cylinders altogether. In the 1950s, a number of companies marketed so-called "tangential" trackers that used dual arms, based on conventional pivoting arrangements, to change the angle at which the headshell was mounted as it moved across the LP side. In 1963, Marantz introduced the SLT-12, which used a plastic pantograph to move the stylus across the record surface. Garrard's Zero 100 pivoting arm controlled its independently pivoting headshell with a bar that extended from the main bearing of the tonearm.

Vivid speakers change the game. But first a great piano recording: <I>Tributaries: Reflections on Tommy Flanagan</I> (CD, IPO IPOC1004), from the late Sir Roland Hanna (his title was an honorary knighthood granted by Liberia). I missed this wonderfully crafted solo-piano recording when it first came out in 2003, and still would not have known about it today except that a publicist sent me an e-mail saying that he was cleaning out his shelves of leftover promotional copies. I quickly sent back a request, in large part because one of my Desert Island recordings is Jim Hall's <I>Concierto</I>, originally released in 1975 on the CTI label, and on which Hanna had played. <I>Concierto</I> has since been reissued in digital form many times, most successfully, as far as I can tell, by Mobile Fidelity Sound Lab on an SACD (UDSACD 2012) that includes new tracks, as well as alternate takes of tunes on the original release.

<I>Never Stop</I> (on the E1 label) is the album from The Bad Plus that many of us have been waiting for—the first of their albums to consist entirely of original material.
