Bob took over the job of "Disc Recording Supervisor" of Motown Records on his 18th birthday. In the first year of employment at Motown he developed his "Loud and Clear" mastering technique, first used on the Supremes hit, "Where Did Our Love Go?" The objective was to get a master that was 20% louder than the competition, yet still "crystal clear" over the radio and when played on the popluar players of that era. By time Bob left Motown he had been given the position as Berry Gordy's Technical Quality Control Supervisor. Bob had to approve all mixes for release, certifying them "Loud & Clear" before release. Mixes not meeting this standard were reported directly to Mr. Gordy so that he could personally suprervise remixing the tune, often sending Bob Dennis into the mixing session to work with the mixing engineer. The Supremes hit, "Love Child" was mixed in this manner.
By 1968, Bob had left Motown for a stint with Holland Dozier Holland's record company, Invivtus Records. Eventually becoming manager of their recording studio, Bob continued his Loud & Clear mastering on another string of gold records. With large record labels raiding the artist rosters of independent companies in the early 1970's, Motown Records ceased recording activities in Detroit in 1972 and Holland Dozier Holland followed suit in 1973.
In 1974, Bob stayed in Detroit and started Superdisc Recording Services, continuing to master hit releases out of the Detroit area, and offering full studio recording services. Also in 1974, Bob started the Recording Institute of Detroit trade school that taught Detroit-style recording techniques. Soon a dozen trade schools around the country began using Bob's outlines for teaching the recording arts. In 1983, Superdisc was split into two companies, Recording Insitute and The Disc Ltd. recording studio (managed by Bob's 35 year partner, Greg Reilly). The Recording Institute Of Detroit is celebrating it's 35th anniversity this year, 2009.
In 1978, Bob became the recording supervisor for George Clinton's production company, Thang Inc. Through the early 1980's Bob acted as associate producer on the many hits George Clinton produced for various national record labels. By 1983 the company had fell on hard times and Bob concentrated on his trade school, authoring a half dozen text books on audio recording & production techniques.
In the mid to late 1990's, Bob was very active in Detroit and Saginaw Michigan, producing local artists and working with the gold award winning songwriter/producer, Dick Wagner. During this time, Bob developed the Recording Institute Of Detroit online services, posting hundreds of articles to the web on recording & production techniques. Tens of thousands of users all over the globe tapped into Bob's writings and his inovative, "Recording Tip Of The Week" series and monthly online magazines.
In the early 2000's Bob designed and helped install Sage Court studios in Ann Arbor Michigan. In partnership with Grammy Nominated, gold-award percussionist Muruga Booker, Bob mixed & mastered several jazz releases on Italy's Qbico label.
in 2006, Bob began publishing online articles on digital signal processing and mastering techniques for use in Recording Institute of Detroit training. In 2009, Bob was invited to do a mastering seminar at the Audiio Engineering Society in New York as a "master engineer" (along with a long-time associate, Bob Olhsson). Bob continues to ocassionally organize seminars at schools and for user groups. Bob's Superdisc Mastering is located at Gospel Sound Sound Studios, Detroit, MI.
