Answer
WhoCares, a short-lived supergroup formed in 1982, brought together legendary vocalist Ian Gillan (Deep Purple) and renowned guitarist Tony Iommi (Black Sabbath). The project showcased their musical chemistry, merging Gillan's powerful vocals with Iommi's heavy riffs. Although the collaboration yielded only one studio album, the eponymous "WhoCares," it left an indelible mark on rock music history.
