The outing will focus on music from the "Fresh Aire" series of albums, which Grammy-winning composer Chip Davis began pumping out in 1974. The final offering in the eight-album series was released in 2000.

Mannheim Steamroller, an ever-changing consortium of musicians, will take 15 performers on the upcoming tour, as well as its trademark multimedia images, synchronized lighting and special effects. The program and cast information is available at the group's website.

The classical rock band, which is Davis' brainchild,, finished its 23rd annual Christmas tour last month and released its eighth album of holiday music, "Christmas Song," in October. The set, which features guest vocalists Johnny Mathis and Olivia Newton-John, climbed to No. 5 on The Billboard 200 and was certified platinum within two weeks of its release, according to a press release.

Mannheim Steamroller, which has logged six multi-platinum-selling Christmas albums since 1984, is the top-selling Christmas act of all time and one of the top 50 best-selling artists of the last two decades, according to its website.

While touring last fall, the group moved into new territory by debuting music from its forthcoming album, "Music of the Spheres." The theme was inspired by recordings that Davis made of NASA shuttle launches.

Davis, who began his career writing advertising jingles in the '70s, has sold more than 36 million albums as an independent artist, making him one of the most successful indie acts in the music industry.
