Using AI to Analyze Music and Video: An A&R Perspective


As the CEO of Iron Gate Records, I am constantly seeking innovative ways to support our artists and enhance their careers. One area where technology is making a significant impact is in the use of Artificial Intelligence (AI) for music and performance analysis. AI has the potential to revolutionize the Artist and Repertoire (A&R) function of record labels by providing detailed insights that can help refine an artist's work and maximize their potential.


In our ongoing efforts to support our artists, I recently utilized AI to analyze a live performance by our band RAINN at a live performance on June 29, 2024.  The band was recorded live on an Android phone doing one of their original songs. I am including a link to the video here so as to allow for your own insights vs. the AI outputs. RAINN - Howl


By creating and refining specific prompts for the AI, I was able to generate a comprehensive analysis of both the music and the performance. This process involved evaluating the song structure, instrumentation, sound quality, stage presence, audience

engagement, and overall execution. The insights gained from this analysis not only highlight the strengths of the performance but also provide actionable feedback for continuous improvement.


This approach underscores the commitment of Iron Gate Records to leverage cutting-edge technology to foster the growth of our artists. By integrating AI into our A&R processes, we can offer a more objective, detailed, and data-driven evaluation of performances, ensuring that our artists receive the best possible support in their musical journey.


The integration of AI into the music industry has revolutionized how A&R executives evaluate and develop musical talent. This blog post explores the benefits and methodology of using AI to analyze music and video performances, drawing from an in-depth analysis of Rainn's band performance.


The following discussion provides the context for such application and a case study for the Iron Gate Records band, “RAINN”.  I also provide a technical overview of how and why this analysis is helpful and part of the overall artist development process.


Objective and Consistent Evaluation

The integration of AI into the music industry has revolutionized how A&R executives evaluate and develop musical talent. This blog post explores the benefits and methodology of using AI to analyze music and video performances, drawing from an in-depth analysis of Rainn's band performance.


One of the most significant advantages of AI is its ability to provide objective and consistent evaluations. Unlike human assessments, which can be influenced by personal biases and emotional responses, AI algorithms offer impartial insights based on data-driven analysis. This ensures that every performance is evaluated against the same criteria, maintaining a fair standard across all assessments.


Technical Precision

AI excels in technical analysis, breaking down various elements of a performance with high precision. For example, in the evaluation of Rainn's performance, the AI analyzed:

  • Vocal Range and Control: Assessing breath control, pitch accuracy, and transitions between vocal registers.

  • Instrumental Proficiency: Evaluating the precision and creativity of guitar solos, rhythm section cohesion, and overall instrumental balance.

  • Cohesion and Interaction: Analyzing how well band members synchronize and interact on stage, indicating good rehearsal practices and musical chemistry.


Efficiency and Comprehensive Feedback

AI can process and analyze performances quickly, providing timely feedback that is crucial for continuous improvement. It can simultaneously evaluate multiple aspects of a performance, offering a holistic view that encompasses technical skill, stage presence, and audience engagement.


Genre-Specific Analysis

AI can be customized to evaluate performances according to specific genre standards. This adaptability ensures that feedback is relevant and actionable. For example, in the context of indie rock, folk rock, and alternative genres, AI can focus on elements like acoustic blending, lyrical content, and innovative musical structures.
