The other, “Van Weezer,” is a detailed homage to the ’80s metal of Cuomo’s adolescence, loaded with the various peacocking techniques — “palm muting, whammy bars, artificial harmonics, two-handed tapping,” per the singer’s rundown — that Weezer consciously rejected as it set out in the dressed-down age of grunge.

The slow movement hovered in polytonal layering, Polonsky’s graceful, repeating chords answered by Kutik’s precise artificial harmonics.

The artificial harmonics in the fifth movement, played on non-open strings and largely in parallel seconds, were otherworldly.

The Ligeti and Radulescu works have much in common, both in overall effect and in specific sounds, like quickly sliding artificial harmonics.

Both natural and artificial harmonics are possible on the double bass, the former being the best; but they are seldom used in orchestral works.
