After Twilight's disband, Holstinin, together with bassist Alik Granovsky, joined rock band Alpha.

Their participation was short-lived, and in 1984 they went to VIA Poyushchie Serdtsa (Singing Hearts) led by producer Victor Vekshtein.

Joined by vocalist Valery Kipelov, they formed a heavy metal band Aria, officially registered as a "side project" to Singing Hearts.

Aria soon developed to be much more popular than original Singing Hearts that played a common kind of Soviet pop-rock music.

Recently he produced some young metal bands; his most notable collaboration was the best-selling Elven Manuscript concept album by Epidemia.
