Thilo Plaesser is far more than just an expert on Mahalia Jackson and her socio-political significance. As an active musician, multi-instrumentalist, author, and experienced improviser, he brings new perspectives to the analysis: He views Mahalia Jackson not only as a historical icon but understands the subtle nuances of her intuitive mastery through daily performance practice. The ability to decipher musical structures while simultaneously appreciating the space for the unpredictable—improvisation—shapes his work. Thilo Plaesser bridges the gap between the spiritual power of gospel and the current call for integrity. As the curator of his significant collection on Mahalia Jackson, he offers readers far more than a printed analysis: his work is distinguished by profound musical expertise, curatorial excellence, biographical authenticity, and visionary interpretive skill.
