Ambassador’s previous owners had the financial backing to run a major concert undertaking, with professional management and a hotshot full-time public-relations director; that’s what brought them Horowitz, Ella, the Berlin Phil and Pavarotti. So far Ambassador has a couple of upcoming concerts in February by the California Philharmonic Orchestra, which plays summertimes at the Arboretum. The program for February 11 consists of film scores including, according to the Web site, "Vivaldi’s The Four Seasons from The Tin Cup." Tickets for Pasadena’s Messiah, by the way, were pegged at a $105 top. There were lots of empty seats, more than I remembered from the good old days.
