In the lead-up to the Pittsburgh (and Pennsylvania) premiere of “As One,” David Bernabo of the web magazine glassblock.com, interviewed composer Laura Kaminsky and visual artist Rebecca Allan. Kaminsky is married to Rebecca Allan, who is represented locally by the James Gallery. The three of them linked up for a discussion about how two artists maintain their shared lives domestically and artistically. How do they navigate these spaces? How does collaboration work out? But they found themselves quickly moving on to the work itself — and especially the political nature of much of their individual and collaborative output.
