Steve Lacy became synonymous with soprano saxophone free jazz, developing one of modern music's most distinctive voices. Stamps, recorded in 2018, finds Lacy working in pure abstraction and extended technique on his instrument. The soprano saxophone becomes something untamed—multiphonics, circular breathing, tonal exploration that ranges from beautiful to unsettling. The music demands active listening; there's no comfortable ground here, only creative risk and artistic integrity. Long-form pieces like "Existence" and "Ire" show a musician still pushing boundaries after decades of work. For listeners seeking genuine avant-garde expression and saxophone virtuosity without compromise.
