After an extensive search, I couldn't find any information on a musician named "Grand Groove." It's possible that the name refers to a song titled "Grand Groove" by Intelligent Hoodlum, released in 1993. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Grand_Groove?utm_source=openai)) Alternatively, "Grand Groove" might be associated with a music label or collective. If you have more specific details or context about the artist you're referring to, please provide them, and I'll be glad to assist further.
