American ambient producer Michael Mantra sadly passed away a few years back, having played a vital role in the development of vibrational and sonic therapy. His theories hugely influenced Echospace duo Stephen Hitchell and Rod Modell, who became close friends with Mantra during the final years of his life. Here they pay tribute to him, creating a piece in three parts inspired by his theories and production methods. It s an all-analogue, drone-influenced soundscape full of dubbed-out textures, meditative white noise and subtle melodic shifts, created in part by using a variety of obscure electronic instruments and experimental production techniques. Sea Shell City is a fitting tribute to Mantras work, and one of Modell and Hitchell s finest ambient works.
