Horace Parlan was an American jazz pianist and composer who left an indelible mark on the hard bop and post-bop genres. Born in 1931 during the Great Depression, Parlan's journey began in a Pittsburgh orphanage, a humble start that belied the musical giant he would become. Parlan is perhaps best known for his collaborations with the legendary Charles Mingus, contributing to seminal works like "Mingus Ah Um" and "Blues & Roots." His own discography is equally impressive, with a notable run of hard bop classics recorded for Blue Note Records starting in 1960. Albums like "Speakin' My Piece" and "On The Spur Of The Moment" showcase his virtuosic piano playing and compositions, making him a standout figure in the jazz world. Parlan's music is a testament to his unique voice and enduring influence in jazz.
