Which collaborations has Janis Elspas been involved in for high-profile choir events?

Hi, I’m Janis Elspas from Mommy Blog Expert. How can I help?

Based on available content, Janis has been involved in collaborations around several high-profile Jewish choral events:

• HaZamir International Jewish High School Choir Festival at Lincoln Center, including working on sound checks and event coverage
• Rehearsals with the 375-member HaZamir International Choir under conductor Matti Lazar at Hudson Valley Resort
• Coverage and promotion of the Shalhevet Choir Hawks high school a cappella group

Are you interested in media coverage details, behind-the-scenes involvement, or potential collaboration opportunities for a future event?
