Bill Marx (pianist)

In the early 1990s, Los Angeles magazine named Marx the most popular lounge pianist in that city. In 2002, he received a star at 265 S. Palm Canyon Drive on the Palm Springs Walk of Stars. Marx still plays as a lounge pianist in and around Palm Springs and Rancho Mirage to this day.

Marx's compositions include concertos for alto saxophone, flute, harp, piano, and violin. He also composed symphonies and scores for films, including the score for the film Weekend Pass (1984).

As a performer, Marx has played in jazz clubs, lounges, and theaters. In the late 1980s, Marx and harpist Carrol McLaughlin toured the United States, giving performances and promoting Harpo Speaks, his father's autobiography. Their concerts featured "exact renditions of songs that Harpo played" and included a segment in which they dressed as Harpo and Chico Marx. They also recorded an album, From Harpo With Love. The duo's schedule for one spring included 42 venues in 21 states over a seven-week span.

In the 1970s, he composed for several low-budget horror movies, including Scream Blacula Scream, Terror at Red Wolf Inn, and Count Yorga, Vampire. For these projects, he often collaborated with lyricist Marilyn Lovell. He continued his work on films outside the horror genre throughout the 1980s, such as arranging music for John Cassavetes' Big Trouble .

In 1961, Marx signed with Vee-Jay Records. His projects there included arranging cover versions of music for four albums by the Castaway Strings. In 1967, he began writing music for commercials.

Marx transcribed music that his father composed, because the elder Marx did not read music. The two worked together on two albums that Harpo recorded in the early 1960s. He also composed and arranged for recording artists in both jazz and popular music.

William Woollcott Marx (born January 8, 1937) is an American pianist, arranger, and composer. He is the first son of actors Harpo Marx and Susan Fleming.
