Which album by Miles Davis became his first gold album certified by the Recording Industry Assoc. of America?

"Bitches Brew", the 27th full-length studio album by American jazz trumpeter Miles Davis, was released on March 30, 1970 on Columbia Records. It marked his continuing experimentation with electric instruments and featured his previous record, the critically acclaimed In a "Silent Way" (1969). With these instruments, such as the electric piano and guitar, Davis departed from traditional jazz rhythms in favor of loose, rock-influenced arrangements based on improvisation.

The album initially received a mixed response, but it gained momentum and became Davis's highest-charting album on the U.S. Billboard 200, peaking at No. 35. In 1971, it won a Grammy Award for Best Large Jazz Ensemble Album. In 1976, it became Davis' first gold album to be certified by the Recording Industry Association of America (RIAA).
