GRAND JUNCTION, Colo. - The song, "Cristofori's Dream," continues to be immensely popular 25 years after composer-pianist David Lanz wrote the piece to honor Bartolomeo Cristofori, the man who invented the piano in the 17th century.The 1988 album "Cristofori's Dream" topped the "New Age" charts and propelled Lanz to international fame for his melodic instrumental music.Lanz began playing piano at 5, and as a young adult played in a number of pop and rock bands in the Pacific Northwest and Canada before gravitating toward playing lighter, solo piano pieces. The music industry "discovered" the new age genre in the 1980s, and Lanz's style of what he has referred to jokingly as "heavy mellow" fit the bill.The album, "Cristofori's Dreams," includes six original songs, as well as Lanz's interpretation of the 1967 classic Procol Harum song "A Whiter Shade of Pale," - a song Lanz will play when he performs a benefit concert in Grand Junction 7 p.m. Saturday, Oct. 20, at Moss Performing Arts Center."I was fortunate to work with Matthew Fisher (original member of Procol Harum and organ player for the song 'A Whiter Shade of Pale')."Fisher played organ on Lanz's rendition of the song on the first album."While I'm more well known as a composer, I always play 'A Whiter Shade of Pale,'" Lanz said.Lanz has arranged a slew of Beatles' songs and recorded two albums - "Liverpool" and "Here Comes the Sun" - songs from which concert-goers can expect to hear at the Grand Junction concert.Lanz said he also plans to offer a "sneak preview of one of the tracks" from a Christmas album due to be released by the end of the year.Along with an assortment of CDs, Lanz will also be selling more than a dozen songbooks after the concert."A lot of piano players come to my shows," Lanz said. "I have sold tons of music books to piano teachers who teach my music to kids."The concert is a benefit for Hospice and Palliative Care of Western Colorado, and the Marsha Thomas Endowment Fund of KPRN/Colorado Pubic Radio. Thomas's daughter, Kellie Caldwell, organized the concert to honor her late mother and raise money for the two organizations that were important to her."David was her favorite piano artist," Caldwell said.The Grand Junction stop is the first part of a tour promoting his new release "Cristofori's Dream...Re-Envisioned." "It's a redone album as a solo piano recording, with a couple of bonus tracks, and a 16-page (liner notes) booklet," Lanz said. The package includes a biography on Cristofori, the story of the original album and lots of photos, Lanz said.To learn more about Lanz's music, visit davidlanz.com.
