Bubbling Under: It's a Yes for NONONO

NONONO holds a bunny aloft in the video for "Pumpin Blood"

Each Friday, Billboard presents "Bubbling Under," a weekly look at new and noteworthy acts making their way toward Billboard chart success. Up this week: NONONO, Doe B, Kevin Ortiz and Ruth La'Ontra.

Following the recent top 10 Billboard Hot 100 success of Icona Pop's "I Love It" comes another Swedish pop confection: trio NONONO makes its first chart appearance with the anthemic, synthesizer-driven "Pumpin Blood" (Warner Bros.), which enters Alternative at No. 39 and Rock Airplay at No. 43. KITS San Francisco leads with 71 plays for the song through Aug. 11, with 27 spins in the Aug. 5-11 tracking week, according to Nielsen BDS. While the band is preparing its debut album, it'll enjoy extra exposure via the song's inclusion in Samsung's new ad campaign.

Montgomery, Ala., rapper Doe B is nearing his first Billboard chart appearance, as "Let Me Find Out" (Grand Hustle/CMB/Interscope) approaches Mainstream R&B/Hip-Hop. Fifty-one stations in the format spun the song last week, translating to 2.1 million in audience, while its remix video, featuring T.I. and Juicy J, has been viewed more than 1.3 million times on VEVO since its June 2 premiere. (The 22-year-old emcee is also known for sporting a patch over his right eye after surviving a gunshot wound in 2009.)

Taking cues from older brother Gerardo Ortiz, 17-year-old Kevin Ortiz is enjoying a quick climb on the regional Mexican scene. Following recent live shows and TV appearances, his single "Un Minuto," written by his big brother, rises 26-22 on Regional Mexican Airplay. Signed to Bad Sin, Ortiz is recording his debut album.

Ruth La'Ontra gains momentum just beneath Gospel Songs with "Count It All Joy," her debut single. The 20-year-old singer is the worship leader at the Come As You Are Evangelistic Center in her hometown of Aberdeen, N.C., where her father, Pastor Arvetra Jones, Jr., is the co-pastor. Signed in April to the Tyscot label roster, La'Ontra is currently working on her debut album.
