BAKER CITY — Anna Tivel opened for Blitzen Trapper at Churchill School, and now she’s coming back with her own band to play Sunday, Aug. 16. Also, admission is free for ages 15 and younger with a paid adult. She’ll be part of a trio for the Baker City show. She tours all over the United States, occasionally overseas, and this year she’ll play some shows in Canada. Tivel will be joined by Sam Weber, a Canadian singer-songwriter, guitarist, music producer and recording engineer.
