Born on July 18, 1975, Daron Malakian became the guitarist, songwriter, and co-vocalist of System of a Down after co-founding the band in 1994. His unconventional riffs, unpredictable songwriting, and willingness to blend heavy metal with Armenian folk influences, punk, and progressive elements helped define one of the most original sounds in modern rock. Albums like Toxicity, Steal This Album!, Mezmerize, and Hypnotize produced classics including "Chop Suey!", "Toxicity", "Aerials", "B.Y.O.B.", and "Question!". Malakian's unique approach to guitar and composition helped make System of a Down one of the most influential metal bands of the 21st century.

Born on July 18, 1938, Ian Stewart was a founding member and original pianist of The Rolling Stones, helping launch the band in 1962 before manager Andrew Loog Oldham removed him from the official lineup because he didn't fit the band's image. Rather than leave, Stewart became the group's road manager and remained their pianist for more than two decades, earning the affectionate nickname "The Sixth Stone." A master of boogie-woogie piano, Stewart played on numerous Rolling Stones recordings while also contributing to sessions with artists including Led Zeppelin, Howlin' Wolf, and Pete Townshend. Though he spent much of his career behind the scenes, Keith Richards often described him as the glue that held the band together. Stewart was posthumously inducted into the Rock and Roll Hall of Fame with The Rolling Stones in 1989, a fitting recognition for one of the band's true founders. :contentReference[oaicite:0]{index=0}

On July 18, 1995, Megadeth released Hidden Treasures, a compilation that gathered rare tracks, soundtrack contributions, cover songs, and previously hard-to-find recordings into a single collection. Originally issued to satisfy growing fan demand, the album showcased another side of the band beyond its studio releases. Highlights included "Angry Again" from the Last Action Hero soundtrack, Alice Cooper's "No More Mr. Nice Guy", the Sex Pistols' "Problems", and the fan favorite "99 Ways to Die", which earned a Grammy nomination for Best Metal Performance. While not a traditional studio album, Hidden Treasures became an essential release for Megadeth fans by bringing together some of the band's strongest non-album material. Produced by Max Norman, Dave Mustaine, Randy Burns, and Mike Clink.
