Guitarist Barry Finnerty remembers his bandmate, friend, and rehab mentor.
"The United States Commerce Department's National Telecommunications and Information Administration (NTIA) spectrum chart, dated October 2003, depicts the radio frequency spectrum allocations to radio services operated within the United States. This chart graphically partitions the radio frequency spectrum, extending from 9kHz to 300GHz, into over 450 frequency bands, and uses distinct colors to distinguish the allocations for the thirty different radio services."

There are three requirements: You must invent a very good loudspeaker that sells for between $1000 and $2000/pair. You have to make enough of them, over a long enough time, to achieve a certain level of brand recognition and market penetration. And you must create a dealer network of reasonable size, with an emphasis on well-promoted specialty shops.
The first time I attended the Las Vegas Consumer Electronics Show, in January 1986, I didn't get there until the second day of the Show. Still, by the beginning of the fourth and final day I'd managed to visit every high-end audio exhibit, and still had time to go back for seconds to the rooms that had sounded the best. Twenty years later, CES has grown so much that it's impossible for a single writer to visit even a quarter of the exhibits in which he might be interested. And even with the sort of <A HREF="http://blog.stereophile.com/ces2007/">team reporting</A> <I>Stereophile</I> now practices, covering the Show has become an exercise in applied logistics for the busy journalist: "Should I wait for the free shuttle bus? Should I get a taxi—though I might get caught in Las Vegas's increasing traffic jams, or even just get stuck at the city's interminable traffic lights? Or should I take the new monorail—though that goes nowhere near the hotel in which [<I>insert name of hot company</I>] is demming its products?"
Tony, a mechanic friend of mine, once ran down for me his "national characteristics" theory of automobile engineering. Germans, he said, love precision engineering but don't take repair into account, so their engines are always placed in wells so perfectly proportioned that skinned knuckles are inevitable. British cars, he said, are marketed to a nation of tinkerers, hence the existence of dual carburetors. And Italian cars? "Well, let's just say they all resemble espresso makers." <I>He</I> said it—and he <I>was</I> the proverbial Fiat mechanic named Tony.
All right, it's time for a pop quiz in Loudspeaker Design 101. Answer the following, and justify your answer.
Let's forget about buying re-releases or back-filling an artist's catalog for a moment, what is the <I>primary</I> way you discover brand-new music to buy?
Back in 1992, <I>Stereophile</I> got into the business of concert promotion when it booked Canadian pianist Robert Silverman for two evenings of recitals in order to record his performances for a live double CD, <A HREF="http://www.stereophile.com/musicrecordings/315"><I>Concert</I></A> (STPH005-2). We don't believe in rushing to repeat a success, so 15 years later, on February 10, we're promoting another concert, this time featuring <A HREF="http://www.myspace.com/attentionscreen">Attention Screen</A>, the quartet led by <I>Stereophile</I> reviewer and jazz pianist Bob Reina.
