When this year’s widespread adoption of COVID vaccines in the Bay Area promised a return to normal, it was a cause for celebration. Unfortunately, people celebrated too early, and the delta variant halted all plans of full reopening for theater performances. For the Oakland Theater Project, which had spent most of the pandemic producing “drive-in” shows, its July opening of “The Dream Life of Malcolm X” — planned as a seated, outdoor show — became one of the many casualties. Three months later and with infection numbers dropping again, OTP is giving in-person performances another shot with its upcoming solo show.
