The Hot Jazz Trio lives up to its name, in that “hot” here means graceful rhythmic intensity, not high volume or bravura tempos. Their instrumentation might seem odd, making some listeners anticipate semipro Dixieland troubadours meandering around a carnival or park, but the trio is anything but amateur. Not only does Persson evoke Bix and Louis (and Arthur Whetsol) in his own solos; he also plays the alto horn delightfully, summoning up both Dick Cary and Juan Tizol. Ullenberger (sic!) is an inspiring rhythm player and soloist, single-string and chordal, as nimble as Howard Alden. He’s listened hard to Eddie Lang and Teddy Bunn, and, like his countryman Holger Gross, he makes the banjo sound pastoral, not industrial.
