When the First Interstate Bancorp. float rolls down Colorado Street in Pasadena, Calif., Jan. 2, it will carry a record number of riders and be the first float in the 100-year history of the parade to have a symphony orchestra and chorale.

Richard Kieffer, president of First Interstate Bank of Utah, an affiliate of First Interstate Bancorp., said the 80-foot float will be a salute to the performing arts and follow the parade theme of "Celebration 100."The first portion of the float is a salute to opera, ballet and drama as represented by six costumed riders. The large middle portion will carry 40 members of the Los Angeles Philharmonic Orchestra and the rear section will feature 20 members of the Los Angeles Master Chorale.

Under the baton of conductor David Alan Miller, the groups will perform "Ode to Joy" from Beethoven's Symphony No. 9.

Kieffer said the float will highlight six urns filled with gladiolas, roses, starburst mums and daffodils. Sculpted roses across the front of the float will be adorned with strawflower, carnations and gladiola petals. Gardens at the base of the float will include roses and orchids.

A marble floor will be created by using sweet rice, rye grass and fescue.

Because the float exceeds the 55-foot limit, it cannot compete for a prize. In this year's parade, First Interstate's "Sophisticated Rhythm" entry won the Mayor's Trophy for originality of design.

The float will be the 85th entry in the 114-unit parade.
