On the lawns of a starred hotel in Mumbai, Chris Martin looks at smartphone photos of a small studio in the bylanes of Parra, Goa. Its walls are full of records of his band, Coldplay , walled and framed, and some photos. He stares intently, and then swipes right, eager to see more. His bright blue eyes widen in delight. “Stuff like this blows my mind,” he says.Martin is frontman and focal point of Coldplay, arguably the world’s biggest rock band today. A few days ago, the British group headlined a massive festival in Mumbai, playing to over 80,000 screaming fans. The band has sold over 80 million records, picked up seven Grammys, and regularly sell out stadiums around the world. Yet, he seems genuinely pleased by the simple act of appreciation by two young Goan fans.So pleased, in fact, that, quite abruptly, Martin signals to one of his crew. She quickly arrives with a small pouch full of small pin-badges with the word ‘LOVE’ printed prominently on them. He pulls out two, and says, “This is my contribution to their shrine.”There are fans, and then there are obsessive superfans. Axel D' Souza and Milind Alvares , both 31, are the latter. They run Hash Cookies, a technology and design firm. “I’ve been a Coldplayer for nearly 12 years now,” says D’Souza. “They inspire me in so many ways. Their music drives my creativity.” So he decided to do what for him was the only logical thing — “it only made sense to dedicate a shrine in their honour at my company’s workplace,” he says. “Now,” he says, eyeing the pin-badges, “the shrine has been blessed by Chris Martin himself.”So, every day, D’Souza and Alvares settle down in front of their workstations, face the Coldplay wall, and get to work. The studio is painted Yellow, “for obvious reasons”.But the love isn’t one-way. “(People like these) have allowed me to have the life I live,” says Martin, visibly enthused. “It reminds me of how grateful I am,” the Coldplay frontman adds, then quips in jest — “Also, these people have amazing taste.”For now, both D’Souza and Alvares are still on a high after seeing their favourite band live. Alvares says, “I knew I’d experience them live one day, but seeing Martin run across the stage waving our tricolour after singing Vande Mataram with A R Rahman; that was more than I could ever have asked for,” he says. Handbands and confetti from the show are the latest additions to the Coldplay shrine. And the simple pin-badges are no less than medals. Will they pin them permanently to their shirts or hats? D’Souza smiles. “They’re gifts from Chris Martin,” he says, and then jokes — “I’m planning on pinning them to my flesh!”
