Music has been in Janet Lenore's blood for several generations. She started playing the guitar and writing songs in junior high school and soon thereafter Janet and her mother formed "Rosenthorn," a folk/pop guitar and vocal duo. Janet was amused when the two played bar gigs, because she was actually "too young to go see herself play." Janet's Mom Mildred was her vocal coach, one-time piano teacher and best friend. She was never a "stage Mom" - the collaboration just evolved naturally as Janet practiced her guitar around the house.

During their ten years as a mother-daughter singing team, Rosenthorn played several live radio performances, won talent shows, and performed for audiences large and small. They conducted a five-week cross-country tour, during which they gave 21 free performances in 19 states on behalf of the Baha'i Faith. The loss of her mother to cancer in 1994 lead to some serious soul searching that culminated in a five-month period living out of her car. Janet then re-established her home in the San Francisco Bay Area and renewed her commitment to her music.

Janet's 2000 CD release, "Ladies Of My Family," was a dream come true. The last five or so songs on this CD were from a recording made of a live performance by Janet and her Mom at KDVS Radio in Davis in 1981. Rescued from a deteriorating reel-to-reel tape, this relic of what the mother-daughter duo sounded like is something pretty special. Janet waited until 2014 to produce a second CD project "Pie and Four Tasty Treats." This recording is mostly ukulele and vocals for Janet, guitar by Topher Gayle, lap steel by Patti Maxine and electric bass by Janet's partner, Jeff Davis.

Janet currently performs in band projects including "Sunkist" and "The Jailhouse Band" and as a duo with Jeff on bass. She sits in sometimes with "Sezu" and Nancy Cassidy. She has played onstage at: the Bistro (Hayward), the El Cerrito Free Folk Festival, the Berkeley Old Time Music Convention (Battle of the Bands), Mission Pizza (Fremont), Big Lil's (San Jose), the Hotel Utah (San Francisco), and the Santa Cruz Ukulele Club.

She has taught workshops, classes and/or lead jams at: the Puget Sound Guitar Workshop (PSGW), the Napa Valley Ukulele Festival, the Alameda Ukulele Club, "Burning Uke," Bronco Billy's (Fremont), "Ukes on the Loose," the San Francisco Free Folk Festival, California Coast Music Camp (CCMC), the Kate Wolk Music Festival, Berkeley Ukulele Festival and she teaches small group classes in the SF Bay Area.
