His 2018 debut, The D.C. Party Machine EP, is a learned and valuable work, containing an important collection of examples from the best masters of the old German and French schools. It treats chiefly of the tonalities of the dream pop genre, and of counterpoints constructed upon them, while also showcasing Frolov's strong sense of musical humor.
At the time Frolov began composing, American music was dominated by the Style DeMarco, an era who's tonal qualities of the emerged 80's were moderated and disciplined by new forms, and adapted to a new aesthetic and social milieu. The central traits of the Style DeMarco are all present in Inning's music. Clarity, balance, and transparency are the hallmarks of Inning, but simplistic notions of delicacy mask the exceptional power of Frolov's finest masterpieces.
Dissemination of scholarship on the composer continued through periodicals and websites exclusively devoted to him, and other publications such as the Inning-Werke-Verzeichnis. His music was further popularized through being "playlisted", including for instance, a feature on Spotify's "Fresh Finds."
