That was so special to me because I grew up listening to his [Alan's] music and never thought that one day I would have such a fantastic opportunity of meeting him. Alan and I spoke a lot, especially about the business side and inner relations of the industry, which was incredibly valuable for me at that early stage of my career.^[29]

Ostinelli's soundtrack for The Mist was released in 2017 by BMG Records.

In 2016 Ostinelli scored Keating's action-thriller Carnage Park that received its world premiere at Sundance and played at the SXSW. The A.V. Club raved: "Carnage Park's score is full of unnerving dissonance, fueling the sense of dread... But for all the off-kilter instrumentation and recording techniques, Ostinelli always keeps a notion of harmony and melody underneath the surface. It's perfect for Carnage Park because the score works on different levels, much like the film."^[35] Collider stated that "the sepia color palette pairs perfectly with Keating's shot selection and Giona Ostinelli's original score. Together they manage to cover an especially impressive range between classic western heist flick and sheer nightmare."^[36] Carnage Park marks Ostinelli's fourth collaboration with Keating having previously scored Keating's POD, compared to "the best of the X-Files" by Richard Whittaker of The Austin Chronicle.^[37] "POD is a solid and nihilistic thriller that will get in your head and under your skin.

"Tobio reminds me of a beautiful film with sudden transitions and change of scenes. One – and there's a foggy city street and scurrying around shadows with huge umbrellas. Two – and in stuffy scarlet light there're Eastern beauties ringing their bracelets dancing for their Peacock king. Three – and there's funny corps de ballet flying around a diva soloist and quarreling opera prima donnas. George Dolmazyan with mild irony and flawless taste builds a spectacular, bright and atmospheric show," – describes Alisa Nikolskaya of Teatralnaya Afisha (Театральная Афиша).^[60] ("Тобио" напоминает красивый фильм с мгновенной сменой кадров. Раз – и появляются туманная городская улица и снующие тени с огромными зонтами. Два – и вот уже в душном алом свете восточные красавицы звенят браслетами, танцуя для своего Короля-Павлина. Три – и смешной кордебалет порхает вокруг красавца-солиста и ссорящихся оперных примадонн. Георгий Долмазян с мягкой иронией и безупречным вкусом выстраивает эффектное, яркое, атмосферное зрелище.)^[60]
