'In Concert' is a live double recorded in 1972 at the Philharmonic Hall in New York City. This album brings the funk from the outstanding studio sessions that brought 'On The Corner', with a taste of the sonic boom captured in 'Agharta' and 'Pangaea'. "Rated X" kicks off the album starting from a rhythmic babble to a swelling wave of funk, until Mike Henderson enters in the middle of Miles's wah-wah trumpet solo. Throughout the concert its Mtume's congo's, Badal Roy's tabla's and Khalil Balakrishna's sitar that make this album a spicey world music gumbo, another brew that Miles masterfully stirs with his trumpet.
