I "discovered" these young ladies last year. They just put out a Christmas album of covers and one original song. It's excellent. They are 25 years old and love 60's music. Their harmonies are AWESOME and they both play multiple instruments. SO talented! Check them out. https://monalisa-twins.com/
While there are some new songs out there I like, when it comes to Christmas music I'm typically very old school. This gentleman is one of my favorites-- awesome voice. Grew up hearing his songs played every year.
