For Jewish music I would go for Avrohom Fried (especially until the Bein Kach U’Bein Kach album) and anything that Abie Rottenberg says let alone sings!
When it comes to non Jewish Musicians nothing beats Yanni. If you would like to know which Yanni songs then it is Acroyali-Standing In Motion and Swept Away from his album and video Live at the Acropolis it is just incredible!!
