Playing a 1:30 p.m. show in the scorching heat didn't deter Milwaukee native Grace Weber in her debut Summerfest appearance Saturday afternoon on the Miller Lite Oasis.

The 23-year-old doesn't fit the typical singer/songwriter stereotype, which usually includes a guitar played by a female sharing her tales of scorn or dispair over relationships that went sour.

Weber, meanwhile, masterfully blends touches of jazz, blues, gospel and pop into a friendly, and almost festive mix. Her backing band of Julian Pollack (keyboards), Lee Pardini (bass), Adam Jackson (drums) and Deen Anbar (guitar) were up to the challenge, each adding their own unique twist behind Weber's vocals.

Members of the Rodney Cunningham Singers, a local gospel outfit, provided a very nice touch on background vocals.

Included in the 45-minute show was a spectacular cover of Mumford and Sons' "Little Lion Man," which Pollack supported on the keyboard, and a genuine, heartfelt love letter to her home and family in "&Heart."

Weber's career is just getting started, but she's already earned significant national attention with appearances on the "Oprah Winfrey Show" and "Good Morning America."

With her debut album set for release later this fall, she can probably expect her next Summerfest appearance to come a little later in the day.
