Singer/songwriter Jewel debuted three songs during an hour-long concert Tuesday night at the Hudson Theatre in New York's Millennium Hotel.

Though she is not on tour, but rather penning new material from her Texas home, the pop-folk singer performed as part of a concert co-sponsored by RCA and Radio Shack. The concert will be broadcast on televisions in Radio Shack stores beginning Thursday and will run until the end of the month.

Opening the show for the crowd of 300 was singer/songwriter Lyle Lovett. The Texan performed some of his older songs, including "If I Had a Boat," off 1988's Pontiac, and "Good Intentions," from Lyle Lovett and His Large Band (1989).

Jewel, whose most recent release was Joy: A Holiday Collection, in December, performed a set of hits that included "You Were Meant for Me," "Foolish Games" and "Who Will Save Your Soul" (RealAudio excerpt) from her debut album, Pieces of You (1995). She then moved on to more upbeat hits, such as "Down So Long" (

"My voice is kind of hoarse tonight," Jewel said between songs. "Sorry about those high notes."

Nevertheless, the 25-year-old singer, looking decidedly sophisticated in an orange silk dress and black high heels, was energetic and in high spirits as she strapped on an electric guitar to belt out a new, rock-country tune that took her into Bonnie Raitt territory. Other new offerings included a Bob Dylan-esque folk song about living (and loving) in Texas, as well as a ballad that Jewel told the audience was about a friend who recently died of cancer.

The concert was part of a special RCA-Radio Shack promotion to announce that Radio Shack is now selling RCA digital audio and video products. The alliance of the two companies will kick off with an international music series called "Music in High Places," which films musicians playing at international sites such as Peru’s Machu Picchu and Egypt’s Great Pyramids. According to RCA, Jewel will film an episode for the series.
