Welcome to the March installment of Aquarium Drunkard’s recurring Transmissions podcast, a series of interviews and audio esoterica. This month, we’re centering in on a sense of place. First, we sit down with author and musician Ryan H. Walsh to discuss his new book, Astral Weeks: A Secret History of 1968. In ’68, Boston was roiling with counter-culture activity. Occult circles were thriving; the underground press was emerging; the Velvet Underground, on loan from New York, was playing transcendent sets at the Boston Tea Party. And through it all, Irish R&B singer Van Morrison was quietly — and often not so quietly — tapping into the vibes that would help birth his soul-folk masterpiece, Astral Weeks. Walsh, best known for his work with the indie rock outfit Hallelujah the Hills, details it all in his personal and poetic new book.

Next, guitarist and writer William Tyler sits down with Douglas Mcgowan of Yoga Records and Numero Group to discuss the process of turning the pioneering vinyl soundscapes series Environments into a functional, immersive app for iOS devices. Designed with relaxation and contemplation in mind — to aurally transport listeners to settings of tranquility — the app recontextualizes sound recordist Irv Teibel’s original aim of providing calm and peace in a noisy world, redefining the notions of a “reissue” in the process.

And finally, we close out the show with a look at our Abstract Truths: An Evolving Jazz Compendium mixtape series, which offers jazz collectors and thinkers a platform for exploring what jazz means in 2018, examining its past, untold stories, modern resonance. Where is jazz going? And what unique role does Los Angeles play in its future?
