Here's another article about this concert that sheds some light on why this Jewel concert is only one night with an orchestra. It's a series of 8 concerts each with different artists:

LeAnn Rimes and Boston Pops Orchestra to Kick Off Unique Series in Boston on May 23


Pairing popular recording artists with symphony orchestras in "one night only" engagements, Elevation Entertainment, a Los Angeles and Cleveland-based entertainment marketing and promotion company, has announced the launch of a new concert series, Argent Mortgage Orchestrated™.
The concept of Argent Mortgage Orchestrated™ is to present popular artists in the opposite environment of the critically acclaimed "MTV: Unplugged" format. Instead of stripping music down to the core, the series will offer artists an unconventional opportunity to perform their songs in ways that they choose, with the full backing of some of America's finest symphony orchestras. Each concert will be a "one night only" engagement and staged in intimate, beautiful concert facilities. The series will present up to eight (8) live concerts in various cities across the U.S. during 2005.

The first three concerts will feature multi-platinum recording and award winning artists. The series will open in Boston's Symphony Hall with Grammy Award winner LeAnn Rimes and the Boston Pops Orchestra on May 23. The second show, at Minneapolis' Orchestra Hall on June 13, will feature a second Grammy Award winner, Seal, who will perform with members of the Minnesota Orchestra. The third show will feature Jewel performing with the Cleveland Pops Orchestra at Cleveland's Cain Park on July 30. All information related to additional concerts will be released shortly.
