Sharp versus continuous. Forgotten and abiding. Diatonic into toneless. Juxtaposition defines “Dream Walk,” a 12-minute spree from the violinist Jason Kao Hwang’s latest album, “Sing House,” due May 5. His quintet jostles from occasional moments of unison playing into wide-burning group improvisations. Like much in Mr. Hwang’s catalog, this stuff feels both intensely personal and oddly mythic. The performance ends slowly, gravity setting in, a wafting sense of peace in lieu of resolution. The quintet from the album — Steve Swell on trombone, Chris Forbes on piano, Ken Filiano on bass and Andrew Drury on drums — performs Friday at Soup & Sound, a house venue in Brooklyn. - Giovanni Russonello, The New York Times  Read NYT article
