To sustain nearly an entire hour of music for solo trumpet is no one’s idea of easy. When Ambrose Akinmusire took on the challenge with this engrossing solo recital, he was about to start a new chapter with Nonesuch, after a highly successful five-album run on Blue Note. Beauty Is Enough has the feeling of a transition, a clearing away to get to the essence. It could be called “one instrument is enough,” for in this player’s hands the horn conveys a wealth of sound, rhythm, and compositional range, from the angular intensity of “Launchpad,” “2-> 1<-” and “Wallace” (likely for the late trumpeter Wallace Roney) to the meditative long tones of “Olusiji SR” and “To: Taymoor.” Akinmusire’s lyricism is sublime; his extended techniques (cracked notes, flutters, overtones) give the music a sense of tension and imperfection. He’s also developed a way to dialogue with himself in two registers, as on “To: Shabnam,” “Cora Campbell,” and “Carvin.” The expansive reverb on the trumpet becomes almost part of the instrument, strikingly so at the beginning of “-Ann_.” Hearing that room-filling resonance die away at the end of each track feels like part of the music as well.
