Dolphy occasionally recorded unaccompanied saxophone solos; his only predecessors were the tenor players Coleman Hawkins (most notably "Picasso", 1948) and Sonny Rollins (for example "Body and Soul", 1958), making Dolphy the first to do so on alto. The album "Far Cry" contains his performance of the Gross-Lawrence standard "Tenderly" on alto saxophone, and, on his subsequent tour of Europe, Billie Holiday's "God Bless the Child" was featured in his sets. (The earliest known version was recorded at the Five Spot during his residency with Booker Little.) He also recorded two takes of a short solo rendition of "Love Me" in 1963, released on "Conversations" and "Muses". Twentieth-century classical music was also part of Dolphy's musical career. He was very familiar with the music of composers such as Anton Webern and Alban Berg, and had a large record collection that included music by these composers, as well as by Debussy, Ravel, Stravinsky, and Bartók. He performed Edgard Varèse's "Density 21.5" for solo flute at the Ojai Music Festival in 1962, and participated in Gunther Schuller's and John Lewis's Third Stream efforts of the 1960s. Dolphy also admired the Italian flute virtuoso Severino Gazzelloni, after whom he named his composition "Gazzelloni". Around 1962–63, one of Dolphy's working bands included the pianist Herbie Hancock, who can be heard on "The Illinois Concert", "Gaslight 1962", and the unissued Town Hall concert with poet Ree Dragonette. In July 1963, producer Alan Douglas arranged recording sessions for which Dolphy's sidemen were emerging musicians of the day, and the results produced the albums "Iron Man" and "Conversations", as well as the "Muses" album released in Japan in late 2013. These sessions marked the first time Dolphy played with Bobby Hutcherson, whom he knew from Los Angeles, and whose sister he dated at one point. The sessions are perhaps most famous for the three duets Dolphy performs with bassist Richard Davis on "Alone Together", "Ode To Charlie Parker", and "Come Sunday"; the aforementioned release "Muses" adds another take of "Alone Together" and an original composition for duet from which the album takes its name. In 1964, Dolphy signed with "Blue Note" and recorded "Out to Lunch!"
