Biography

Japanese punk/psychobilly rock unit The Birthday are a project of vocalist Yusuke Chiba and guitarist Akinobu Imai of the J-rock band Rosso. Both men drifted away from Rosso in 2006 and created Birthday after a short stint as a duo under the name Midnight Bankrobbers. The new band found its rhythm section in drummer Kazuyuki Kuhara, with whom Yusuke used to play in Thee Machine Gun Elephant, and bassist Haruki Hirai, and then wasted little time, debuting with the single "Stupid" in the summer of 2006. The first studio album, Rollers Romantics, also arrived in 2006, supported by a Japan-wide tour. By the time of their second album, Teardrop (2007), The Birthday were already big enough to play the country's number one venue, the Budokan, with the show documented on the DVD Looking for the Lost Teardrops Tour Final. The band kept to the yearly schedule, releasing third album Night on Fool in 2008 following the Motel Radio Sixty Six EP issued earlier that same year. ~ Alexey Eremenko, Rovi

Artist Affinity estimates how strongly an artist's audience overlaps with interest in specific brands, products, and categories. It is derived from aggregated social and behavioral signals—who fans follow, save, click, and engage with—normalized across platforms. Higher affinity suggests better partnership fit and higher likelihood that fans will respond positively to branded content or offers. Use it to shortlist natural brand partners and product concepts that feel authentic to the audience. Combine affinity with Connection Strength (ER) and reach to balance fit with impact. Treat affinity as directional—validate with creative tests and small pilots before scaling.

ER = (likes + comments + shares) ÷ audience per post ≥ 3.0% = Very Strong 2.0–2.99% = Strong 1.0–1.99% = Moderate < 1.0% = Low

How to read it: Pair ER with reach (views/followers) to gauge intensity and scale.
