What is Mark Andes' Net Worth?

Mark Andes is an American musician who has a net worth of $4 million. Mark Andes is best known as a bassist whose career has connected several major chapters of American rock history. He was a founding member of Spirit, co-founded Jo Jo Gunne, became an original member of Firefall, and later played bass for Heart during one of the band's biggest commercial eras. Over the course of his long career, Andes has worked in psychedelic rock, country rock, soft rock, hard rock, session music, and roots-oriented projects.

Mark Andes' most famous credits include Spirit albums such as "Spirit," "The Family That Plays Together," "Clear," and "Twelve Dreams of Dr. Sardonicus," Firefall albums including "Firefall," "Luna Sea," and "Élan," and Heart albums including "Passionworks," "Heart," "Bad Animals," and "Brigade." Although he has often worked outside the spotlight, Andes has been a key supporting figure in multiple bands that produced major albums, classic-rock radio staples, and long touring careers.

Early Life

Mark Andes was born on February 19, 1948, in Philadelphia, Pennsylvania. He grew up in the Los Angeles area and came from a show-business family. His father, Keith Andes, was an actor whose credits included film, television, stage, and voice work.

Mark developed as a musician during the 1960s, when Los Angeles was becoming one of the most important centers of American rock. As a teenager, he was briefly connected to Canned Heat before the band became nationally known. That early experience placed him near the center of the Southern California rock scene.

Spirit and Jo Jo Gunne

Andes became a founding member of Spirit, the Los Angeles band known for blending rock, jazz, psychedelia, and progressive ideas. The group's original lineup included Jay Ferguson, Randy California, Ed Cassidy, John Locke, and Andes on bass. Spirit released its self-titled debut album in 1968, followed by "The Family That Plays Together," "Clear," and "Twelve Dreams of Dr. Sardonicus."

Spirit never became a massive mainstream commercial act on the level of some of its late-1960s peers, but the band became highly respected among musicians and rock fans. Andes' bass work helped give Spirit its fluid, jazz-influenced foundation.

After leaving Spirit, Andes and Jay Ferguson formed Jo Jo Gunne. The band released its debut album in 1972 and scored a hit with "Run Run Run." Andes' brother, Matt Andes, also played guitar in the group. Mark left Jo Jo Gunne after its first album, but the project added another important chapter to his résumé as a founding member of a notable 1970s rock band.

Firefall

In the mid-1970s, Andes became part of Firefall, a country-rock and soft-rock band formed in Colorado. The original lineup included Rick Roberts, Jock Bartley, Larry Burnett, Michael Clarke, and Andes, with David Muse joining as an important multi-instrumentalist.

Firefall's 1976 self-titled debut album became the band's breakthrough. It included "You Are the Woman," which became a Top 10 pop hit and the group's signature song. Firefall followed with successful albums including "Luna Sea" and "Élan," building a reputation for melodic, polished country-rock with strong vocal harmonies.

Andes' bass playing was part of Firefall's classic sound during the band's most commercially important years. He later rejoined the group decades afterward, returning to the Firefall name for live performances and later recordings.

Heart

One of the most lucrative and visible periods of Mark Andes' career came when he joined Heart in the early 1980s. The band was built around sisters Ann Wilson and Nancy Wilson, who were Heart's lead creative forces and most recognizable members. During Andes' era, the lineup also included drummer Denny Carmassi and keyboardist Howard Leese, with Mark playing bass.

Andes first appeared with Heart on "Passionworks" in 1983, then remained through the band's huge commercial comeback. He played on Heart's 1985 self-titled album, which became the band's only No. 1 album and produced major hits including "What About Love," "Never," "These Dreams," "Nothin' at All," and "If Looks Could Kill."

He also played on "Bad Animals," which included the No. 1 hit "Alone," and on "Brigade," which featured "All I Wanna Do Is Make Love to You." During this era, Heart became one of the biggest arena-rock acts in America. Andes' time with the band gave him his largest mainstream platform and connected him to a run of multi-platinum albums, major tours, music videos, and radio hits.

Later Work

After leaving Heart, Andes continued working as a session musician, sideman, and touring player. He collaborated with artists including Robert Mirabal, Iain Matthews, Alejandro Escovedo, Ian McLagan, and others. He also released solo material, including the album "Real World Magic."

Andes later lived in Texas and remained active in music through performances, collaborations, and Firefall-related work. His career has been defined less by solo stardom than by longevity, adaptability, and the ability to fit into several very different bands at important moments in their histories.

Personal Life

Mark Andes has been married to Valerie Andes and has lived in Texas. He has generally kept his personal life private, preferring to be known through his music rather than celebrity culture.

His career stands out because he was not simply a sideman for one successful act. He was present for key periods in Spirit, Jo Jo Gunne, Firefall, and Heart, giving him one of the more unusual résumés among classic-rock bassists.
