Two different anniversaries are the focus of this 2014 anthology by composer Chip Davis' world-famous new age ensemble Mannheim Steamroller. The 30 in the album's title refers to the three decades since the release of their wildly successful Christmas collection, an album that would eventually go platinum six times over and inspire a bevy of sequels and tours, essentially turning the band into a veritable holiday industry. The 40 refers to Davis' debut album, Fresh Aire, which arrived a full decade before the Christmas album. Blending symphonic sounds with synthesizers and rock instrumentation, the first groundbreaking Fresh Aire album went gold and became the flagship name under which Mannheim Steamroller would operate for the next 40 years. The 30/40 collection takes a look back, offering 15 remastered tracks from both the Christmas and Fresh Aire series of albums as well as a new rendition of "Greensleeves" sung by Davis' daughter Elyse.
