The album commences with two jazz standards, including Gershwin's aria "My Man's Gone Now," which Evans had notably recorded live during his famous 1961 Village Vanguard sessions.

Writing for AllMusic, music critic Michael G. Nastos notes of the album: "A duet recording between pianist Bill Evans and guitarist Jim Hall is one that should retain high expectations to match melodic and harmonic intimacies with brilliant spontaneous musicianship.

Where this recording delivers that supposition is in the details and intricacy with which Evans and Hall work, guided by simple framings of standard songs made into personal statements that include no small amounts of innovation.

... At only 32 and a half minutes, it's disappointing there are no bonus tracks and/or additional material for a CD-length reissue, but Intermodulation still remains a precious set of music from these two great modern jazz musicians.

"[3] Evans's biographer Peter Pettinger notes that "the textural and creative amalgam of their earlier Undercurrent was perpetuated, the complementary interweaving of solo and supporting roles again done to perfection."
