Spring fever is heading to town, and it’s infecting the population with the sweet sounds of jazz. Resisting is useless, so perhaps it’s best to head straight to the heart of the matter in Calistoga for the Spring Jazz Festival this weekend. Each ticket provides access to live jazz in a tent pitched downtown, as well as 10 tastings of local wine and cuisine. Capitulation to spring fever will never feel better while sipping on some Castello di Amorosa or Chateau Montelena and listening to the sounds of saxophonist Devin Phillips, guitarist Rolando Moralas, vocalist Billy Valentine and many others. The fever continues with more jazz and fun on Sunday for brunch. Succumb to the music on Saturday, March 10, downtown Calistoga. Noon. $36. 707.942.6333.
