He was raised in an Orthodox Jewish family, and attended Greenfield Hebrew Academy and Yeshiva High School Through his mother, he is related to actor Logan Lerman. In the late 1990s and early 2000s, Lowenstein recorded with his identical twin brother, Evan, in the pop duo Evan and Jaron. Evan and Jaron charted three singles, including "Crazy for This Girl," which reached number 15 on the BillboardHot 100 charts in 2000. The duo split up in 2003 so that Evan could focus on raising his family. Jaron co-wrote and recorded his first solo single, "Pray for You", as Jaron and the Long Road toLove in late 2009. Starting in February 2010, Big Machine Records assumed promotion of the single and a forthcoming album, which was distributed through a partnership of Jaron's Jaronwood label and Universal Republic. The song reached Top 40 on the Billboard Hot Country Songs chart and the Billboard Hot 100. Jaron told Technorati that the song "wasn't started or pushed by some major label or organization. I would love to take the credit for its success, but honestly this is something fans want and they are the ones calling radio to have them play it." Hank Friedmann directed a music video for the song, which has aired on CMT Pure Country and Great American Country. A second video, which includes Jaime Pressly, debuted in April 2010. His debut album, Getting Dressed in the Dark, was released on June 22, 2010. The album's second single is "That's Beautiful to Me", which debuted on the country chart at number 59 in September 2010.
