You may be thinking of Pomplamoose, a musical duo known for their creative, homemade music videos and indie/folk sound. However, Pomplamoose consists of Jack Conte and Nataly Dawn (not Eddie Rosenberg and Heather Herschfield), and they are a romantic couple, not siblings. They became popular on YouTube in the late 2000s for their inventive covers and original songs filmed in a split-screen style. The 'green orbs' reference is unclear - it might relate to visual elements in their videos or you may be conflating details from different artists. I cannot find any musical duo matching the specific names Eddie Rosenberg and Heather Herschfield with a 'green orbs' connection. If you can provide additional details about where you encountered this act or their music, that would help identify them more accurately.

The answer correctly identifies that the user's provided names (Eddie Rosenberg and Heather Herschfield) and relationship (brother and sister) do not match Pomplamoose. The details provided about Pomplamoose (Jack Conte and Nataly Dawn, romantic couple, indie/folk) are factually accurate. The primary 'error' is the initial suggestion of Pomplamoose, as it doesn't align with the user's core identifiers (names, relationship, 'green orbs'). While the answer immediately points out these discrepancies, it dedicates a significant portion to an artist that is not a match. The answer correctly concludes that it cannot find a duo matching the user's specific, unique details, which is likely because such a duo with those specific attributes does not exist as described.

Score: 8
The answer correctly identifies Pomplamoose as a musical duo known for their creative videos and indie/folk sound. However, it fails to directly address the original query about 'green orbs' and the specific names Eddie Rosenberg and Heather Herschfield, which are not associated with any widely known musical act. While it correctly notes that Pomplamoose is not comprised of siblings, it does not clarify the potential confusion stemming from the 'green orbs' reference or suggest any other well-known duo that fits the description. The suggestion for the user to provide additional details is constructive, but the response could benefit from a clearer exploration of the 'green orbs' concept or alternative suggestions.

The answer is mostly accurate and comprehensive. It correctly identifies Pomplamoose as the duo in question, acknowledging the 'green orbs' reference as unclear while offering a plausible explanation. It also provides a detailed description of Pomplamoose's style and members, clarifying the relationship between them. The only potential improvement could be made by conducting further research to definitively identify the 'green orbs' reference. While the answer suggests it might relate to visual elements in Pomplamoose's videos, a quick review of their content doesn't reveal any obvious green orbs. A deeper dive into their visual style or an exploration of other artists with similar aesthetics might yield a more concrete connection.
