READERS' PICK: Voters were vague about which TSO performance was best, but one did mention the special concert with guitarist Christopher Parkening in February. That was a good one, but the orchestra, under independent-minded music director George Hanson, provided several evenings of symphonic rapture. And not just Rapture, a newish piece by Christopher Rouse, but everything from balanced Beethoven to sensational Shostakovich. Perhaps best of all was May's irresistible Latin-American program, led by the witty and vigorous Enrique Arturo Diemecke.
