On his 14th Criss Cross leader album, titled Reverberations, Alex Sipiagin booked a six-concert tour in November by a sextet of long-time friends and bandmates from several years of activity that constitute his thriving career. After a few days off, they convened at a well-appointed studio in Bassano del Grappa, the grappa capital of Italy, a 10-minute drive from Sandrigo, the village in the north Italian region of Vicenza, where Sipiagin resides with his wife. “My improvisations and compositions have more space, more air, more stopping to process what I feel,” Sipiagin, now 58, said, “Living here, you can breathe, create and practice.” On Reverberations you can feel that attitude suffusing the contributions of Will Vinson and John Escreet, both U.K.-born, the formidable Berlin-based Russian expat bassist Makar Novikov, and Donald Edwards, a son of Baton Rouge and New Orleans, Louisiana. “There’s nothing super-complicated except a few melody heads,” Sipiagin says. “We took our time and relaxed, played it in the same order as the concerts, and it came out quite spontaneously.”
