Music to soothe the mid-winter soul

"Telluride Sessions" by Strength in Numbers has superb musicianship throughout. Although all the cuts might not be considered soothing, "One Winter's Night" is exactly the tonic you seek. If it doesn't touch your soul...You haven't got one.

Classical as mentioned, is an antidote for sure. In addition, I've been rediscovering Donovan and finding his music, once again, very thought provoking and uplifting. I've got early vinyl, but Donovan's Greatest Hits on Epic and numerous other CDs are quite good.

Abattoir blues / The lyre of Orpheus

How about some Blackmore's Night?

If not the musical act then perhaps Blackmore's Night (Candice) herself?

Sibelius!
