Bubbling Under: Kat Dahlia's Debut 'Gangsta' Blazes Onto Radio

RDGLDGRN
Virginia-based RDGLDGRN is approaching the Alternative Songs chart with "I Love Lamp" (Fairfax/Republic), led by 28 plays in the March 4-10 tracking week at KKDO Sacramento, Calif. The band released a four-song EP last month ahead of its planned debut full-length. The group's members, each of whom dresses in red, gold and green, respectively (as the act says it views the world as a harmonious rainbow), employed rock luminary Dave Grohl to play drums on the EP after he was impressed by a demo of "Lamp."

Gimm+Icky
Pop duo Gimm+Icky is quickly rising up the Dance/Club Play Songs chart with its debut chart hit, the infectious "Shake That" (HitShop). The track, supported by remixes from the likes of Jump Smokers and Papercha$er, flies 44-28 in its second week on the DJ-based survey. The act (Tripp Weir and Jeff Garrison) formed in 2011 and has seen its music synched on E!, Nickelodeon, the NFL Network and ABC-TV's "The Middle."

Joel Crouse
With spins at 67 of the 127 stations monitored for the chart, Joel Crouse's debut single "If You Want Some" gains momentum on Country Airplay, where it reaches a new peak with a 48-46 lift in its seventh week. The 20-year-old singer/songwriter, who's prepping his first album,  is signed to Toby Keith's Show Dog-Universal label and has opened for Keith, as well as Darius Rucker and Sara Evans.
