The emotional, abstract, and colorful work of Toby Salkin in her solo show “80 Going on 20” will be steps away from the imaginative, precise, and often other-worldly presentation Jonathan Burke’s “Nothing Happens at Once” at Topanga Canyon Gallery. The two shows run concurrently from August 19 through September 4, with an opening reception Saturday August 20th from 3 – 7 PM.
