“Believe in a little bit of magic.” HBO has revealed an official trailer for another fascinating new Music Box documentary film titled Happy And You Know It, the latest mesmerizing cinematic creation from the wonderful doc filmmaker Penny Lane. Subverting the notion that making music for children is easy and proving that love, imagination, and emotional truth are the foundations of songs that resonate, Happy And You Know It reminds us of the magical way music connects us across generations and to the child inside us all. The doc dives into the surprisingly powerful world of children’s music, uncovering origin stories of the artists who shaped the genre. It chronicles the unexpected paths musicians take to embrace the creative freedom found in writing music that shapes childhoods. Featuring conversations with talented musicians like Anthony Field of “The Wiggles”, Chris Ballew, Divinity Roxx, Laurie Berkner, Johnny Only, and many others. I’m a big fan of Penny Lane’s other Music Box doc Listening to Kenny G and this one looks just as good. I’m glad Penny tells this story in such a bright, beautiful, uplifting way – it is definitely worth a watch.
Here’s the full official trailer (+ poster) for Penny Lane’s doc Happy And You Know It, from YouTube:
