Evidently there is a market for Sephardic (Ladino) rockn' roll. Sarah Aroeste debuted her Ladino rock ‘n’ roll band back in 2001. She apparently quit her day job to do it as well. It seems from the article she might be shomer Shabbat:"where Ladino songs graced the record player and the Shabbat dinner table. The Yale-educated soprano further fell in love with the ancient art form while studying at a Tel Aviv opera summer program eight years ago."
Hopefully they were not playing the records at the shabbat table.
