Joseph Louis LaBracio (September 5, 1932 – April 21, 2021), better known by his stage name Joe Long, was an American musician.

He was best known for his tenure as the bass guitarist and vocalist for the Four Seasons from 1965 to 1975, having succeeded original bassist Nick Massi in those positions.

Long was a classically trained musician who studied with Alfonse Strazza, the principal bassist for the New York Philharmonic.

[3] For the last several years of his life, he came out of retirement to serve as music director and occasional on-stage member of the Jersey Four, a Four Seasons tribute band.
