Who would have ever guessed that Oakland County would one day become a hotbed of activity for neo-soul and R&B musicians? Hailing from Bloomfield Hills and Farmington Hills respectively, 14-year-old Sofi K is to Jessica Hernandez as Meghan Trainor is to Amy Winehouse. Her debut single “One Way Ticket” would sit comfortably alongside anything in the top 40 right now. This week she will appear at one of the county’s premier concert venues, the Royal Oak Music Theater. Who knows -— pretty soon she might be appearing at the Palace.
