An innovative album that shows the development of the fusion of jazz and hip-hop is Guru's Jazzmatazz Vol 4: The Return of the Jazzmatazz. The Jazzmatazz is back with this album, which includes a variety of guest appearances from both well-known and up-and-coming musicians. The record is a monument to Guru's Jazzmatazz history and his capacity to forge a sound that defies categorization and has a lasting impact on modern music. "State of Clarity," a noteworthy piece on the album, featuring rapper Common and jazz pianist Bob James. James' soulful piano chords are paired with Guru's relaxed flow to create a sound that is both traditional and modern. "Stand Up (Some Things'll Never Change)" is another noteworthy song.
