One of the great recording studios in the Bay Area turned out its lights yesterday. Spark (www.sparkworld.com), located in Emeryville, was a gordeous studio with resonant acoustics and an outrageous 9 foot Yamaha grand. It sold its location to Pixar. The owner, Tony Mills, will continue to do some work - mostly video and post-production, a little audio tracking - out of his home studio in Rockridge. Among the fine albums recorded there was Mark Levine's 2003 grammy-nominated recording "ISLA". I recorded there only once - my 2004 release "Holiday Time" (www.antonjazz.com/cd.html).
