Bubbling Under: Sam and the Womp's U.K. No. 1 'Bom Bom' Hits Stateside

Each Friday, Billboard presents "Bubbling Under," a weekly look at new and noteworthy acts making their way toward Billboard chart success. Up this week: Sam and the Womp, IAmDynamite, the Henningsens and Benjamin Francis Leftwich.

Sam and the Womp
After topping the Official U.K. Singles chart in September, Sam and the Womp's club-ready (and trombone-infused) party anthem "Bom Bom" (Warner Bros.) is making its way stateside. Aided by usage in an international TV campaign for Southern Comfort, which has helped its official video reach more than 12 million YouTube views, the song is winning fans at U.S. mainstream top 40 radio, led by Sirius XM's Hits 1 channel (54 plays in the Nov. 19-25 Nielsen BDS tracking week), KHHM Sacramento, Calif. (28) and WKSE Buffalo, N.Y. (26). The trio is touring the U.K. this month.

Rock duo IAmDynamite is getting fired up on Billboard's charts. The pair's noisy, stripped-down single "Where Will We Go" debuts at No. 40 on the Alternative chart this week. The Brandon/Megaforce-signed act -- Christopher Martin (guitars/vocals) and Chris Phillips (drums/vocals) -- met in high school in Ann Arbor, Mich. The pair has been together ever since and is supporting Sum 41 on tour through early December.

The Henningsens
Having written hits for other artists, family trio the Henningsens are seeking to celebrate their own chart ink with "American Beautiful," which stirs just below the Country Airplay chart. Now signed to Arista Nashville as a recording act, father Brian Henningsen and siblings, Aaron and Clara, scored notable success as EMI Publishing writers, penning the Band Perry smashes "You Lie" (which reached No. 2 on Hot Country Songs last year) and "All Your Life" (a two-week No. 1 in February). The Henningsens hail from Illinois, where they own and operate a family farm; they live in Nashville part-time.

Benjamin Francis Leftwich
English singer/songwriter Benjamin Francis Leftwich is approaching the Folk Albums tally with his EP "In the Open" (Vagrant). The set follows his "Last Smoke Before the Snowstorm," which debuted at No. 10 on Folk Albums and Heatseekers Albums in February. This year, Leftwich played the iTunes Festival in London for the second time, supporting Lana Del Rey. He has subsequently been featured in one of iTunes' "Great New Artist" spotlights.
