Give the gift of music.It wasn’t just a painted sign once splashed across the facade of Janis Music Co., Manteca’s downtown music staple. It’s the family credo.“That’s what we’re all about here,” said Inda Janis.For more than 70 years, the Janis family has traveled the map, giving the gift of music to fans and store patrons coast to coast. Ed and Jeannette Janis founded the Janis Music Co. in Manteca in 1962, but they began sharing their passion for music in the 1940s as members of a big band in Massachusetts.Ed was the leader and Jeannette the lead singer – and soon-to-be wife.
