I have two brilliant plans.
1. Women overwhelmingly gravitate to music with female singers who really convey emotion well. The mistake many people make is get a jazz/lounge type singer and people HATE that. Not to self-promote or anything but. . . Well Laura Iyengar (formerly Gerhard) is as musically intuitive as Gonzalo Bergara in my opinion, has the tone of Jascha Heifetz. In my life I've only seen two standing ovations break out in the MIDDLE of a song, once with Laura, once with Joscho. She is now a resident of North Carolina, we still fly her in to play with us, if you want her to perform on a recording or in a show with you or in a festival I'd be glad to pass on her info. Swing Je T'aime has NO problem attracting a large female audience, we are about 50/50, and I think she well deserves a career outside my group.
2nd Idea: Quinn Bachand, Olli Soikelli, Max O'Rourke, and Daisy Castro all do a tour together. They dress up snazzy, work out, and develop personas - Quinn can be the sweet one, Olli the smooth operator, Max the jock, and Daisy the Bad one. The formula works! That would get BOTH young people AND more ladies into the music. . . two birds with one stone!
