Tomorrow’s Hits: Jonathan Jackson + Enation, Anna Calvi, Marwan (Soulflow)
Each Friday, Billboard presents Tomorrow's Hits, a weekly look at new and noteworthy acts making their way toward Billboard chart success.

Jonathan Jackson + Enation
Jonathan Jackson, 32, has basked in the entertainment spotlight for more than 20 years: he joined ABC’s General Hospital (as Lucky Spencer) in 1993. He reprised his role in 2009-11 and, since 2012, has starred in the network’s Nashville (as Avery Barkley). With music also a muse, he formed Enation in 2004. Now, the rock band is on the rise: its “Everything Is Possible” (Loud & Proud) is nearing Adult Pop Songs. –Gary Trust (@gthot20)
Anna Calvi
English alt-pop singer/songwriter/guitarist Anna Calvi debuts at No. 17 on Billboard + Twitter Emerging Artists with “Piece by Piece” (Domino), marking her first appearance on a Billboard songs chart. Her last set, One Breath, released in October 2013, reached No. 30 on Heatseekers Albums and was nominated for a Mercury Prize. Calvi is currently supporting Morrissey on select tour dates in Europe. –Trevor Anderson
Marwan (Soulflow)
Singer/songwriter Marwan (Soulflow) sizzles under Adult R&B Songs with his neo-soul-tinged “Eternally.” Hometown WSRB and WVAZ Chicago aid in its advance toward the chart: it ranked as each station’s 11th-most played song during the Nielsen BDS tracking week ending Oct. 26. Marwan, who serves as indie label Twoguard’s flagship artist, released parent album Eternal in January. –Amaya Mendizabal (@amayayayaya)
