Musician. He was the bass singer and bass guitar player for the rock ‘n roll group "The Four Seasons". In a close-knit New Jersey Italian neighborhood, he was born Nicholas Macioci. Although it was home, the neighborhood offered little advancement for young men except to join the military, be a part of crime mob or become a performer. After serving in the US Army, he joined with various doo wop vocal groups ending with the Four Lovers in 1958. This group featured also Frankie Valli, Tommy DeVito and later Bob Gaudio, and it was this group that evolved into the Four Seasons by 1960. The group's first #1 Billboard Top 100 hit, "Sherry", was written by Gaudio fifteen minutes before it was recorded in 1961. "Big Girls Don't Cry", "Walk Like a Man" and "Rag Doll" followed as #1 Billboard hits. Other hits included "Dawn" at #3, "Ronnie" at #6. "Stay" at #16, and the last hit featuring Massi was "Let's Hang On" at # 3. Not only could Massi do small bass solo parts in an arrangement, but he could do four-part modern harmonies with the other vocalists. He had a gift for singing that suppressed most of those who studied music. The Four Seasons became well-known not only in America but worldwide, and they held their ground during the British Invasion of many rock groups including the Beatles and Rolling Stones. After being on the Ed Sullivan Show, Nick left the group in September 1965. He stated he was tired of touring and being away from his family. He had married his high school sweetheart Maggie and had a family of three children. Besides, at this point, the group was having much turmoil after receiving the surprising news of the group's financial debt, which had accumulated from poor management over the years. During a tour, he quit on the spot without any strings attached and never looked back. He was replaced by Charles Calello and later by Joe Long. He continued to be in the musical field as an arranger, vocal coach and engineer for numerous New Jersey bands such as the Baby Toys, the Carmels and the Victorians. The Four Seasons were induced into the Rock and Roll Hall of Fame in January of 1990 in New York City and in the Vocal Group Hall of Fame in 1999. "Jersey Boys", a jukebox musical documenting the story of the Four Seasons, opened in 2005, and in 2006 it was a four-time Tony Award recipient including Best Musical. Although Massi had died in 2000 before the opening, he was proudly aware that the musical was in the works. In the summer of 2014, the movie "Jersey Boys" opened. In his later years, Massi, using his birth name Macioci, became an artist with his paintings being sought by fans. He died of cancer on Christmas Eve at home.
