In 1971, she began to play at the Spoleto Festival. In 1977 she and Scott Nickrenz were appointed co-directors of the Noontime Concerts, and they continued in that capacity until 2003, both in Italy and in Charleston, SC. As a result, Robison was awarded the Premio Pegaso and the Adelaide Ristori prizes for her contribution to Italian cultural life. She and Mr. Nickrenz were married in 1971. Together with the harpist Heidi Lehwalder, they toured as members of the Orpheus Trio from 1971 to 1983. Beginning in 1978 until 1990, she toured with the guitarist Eliot Fisk and with the pianist Ruth Laredo. In the late 1970s she was playing at least 100 concerts in a year. She toured Japan in 1978, performing Takemitsu's "I Hear the Water Dreaming" there not long after its premiere in the US.
