The classically trained Uzbekistan pianist Vlad Girshevich is accompanied on Algorithmic Society by famed bassist Eddie Gomez—who was an integral part of pianist Bill Evans’ trio for 11 years—and Girshevich’s 12-year-old son, Aleks, who “created the grooves” that propel his father’s compositions. Things get underway in a hurry on the first track, “Healing the Chaos,” which has Lebanese percussionist Rony Barrak livening up the enterprise. Gomez gets his licks in, too, with some fine arco work here and there and a great solo on the liveliest tune—“A Rainbow on Your Carpet”—with Girshevich pere really flying. Mostly, it’s rather slow going as several tunes are as cerebral as the CD’s title. On Roaring, two-fisted pianist Mike Jones—accompanied by bassist Katie Thiroux and drummer Matt Witek—digs into 10 songs from the 1920s with considerable skill. Tempos range from relaxed (“If I Had You”) to roaring (“I Can’t Believe You’re in Love With Me”). Delightful goods!
