Giuseppi Logan (May 22, 1935 – April 17, 2020) was a jazz musician, originally from Philadelphia, Pennsylvania, who taught himself to play piano and drums before switching to reeds at the age of 12.

Logan played alto and tenor saxophone, bass clarinet, flute, piano and oboe.

He collaborated with Archie Shepp, Pharoah Sanders and Bill Dixon before forming his own quartet made up of pianist Don Pullen, bassist Eddie Gómez and percussionist Milford Graves.

Logan was a member of Byard Lancaster's band and toured with and appeared on records by Patty Waters.

This title was supposed to have been ESP-1018, The Giuseppi Logan Chamber Ensemble in Concert,[1] but this catalogue number was eventually assigned to an album by The Fugs.

He held his head back all the way, explaining once, 'This way my throat is completely open,' so he could have more air coming through his windpipe.

[3]ESP-Disk's Bernard Stollman on Logan: Giuseppi was doing an awful lot of drugs—he burned out, well, actually, he flipped out and never came back.

He would assault people without any warning; I loved his music, however, and when he did his first session, resulting from the October Revolution [ESP 1007, Giuseppi Logan Quartet], Milford Graves and he filed through the studio and as they walked in to record, Giuseppi turned to me and said "if you rob me, I'll kill you."

At one point, I was standing with the engineer in the control room, and I thought the piece they were playing was stunningly beautiful.

[5]Beset with personal problems, Logan vanished from the music scene in the early 1970s and for over three decades his whereabouts were unknown; however, in 2008 he was filmed by a Christian mission group just after he had returned to New York after years in and out of institutions in the Carolinas.

Around this same time filmmaker Suzannah Troy made the first of many short films of Logan practicing in his preferred hangout, Tompkins Square Park.

Subsequently, he was the subject of a major piece by Pete Gershon in the spring 2009 edition of Signal to Noise Magazine, which detailed the events surrounding Logan's "comeback" gig at the Bowery Poetry Club in February 2009.

[8] In April 2010, this group performed a concert in Philadelphia with Dave Miller playing for Warren Smith at the Ars Nova Workshop [9] In October 2011, Logan recorded six songs with "a group of younger experimental musicians"; as of April 2012, he was still living in New York and performing as a street musician.
