Steve Baltin Although Linkin Park’s 2000 debut “Hybrid Theory” is the best-selling debut album of the twenty-first century — diamond-certified by the RIAA for 10 million sales and spawned four hit singles including “In The End” and “One Step Closer,” the band’s Mike Shinoda and Joe Hahn both admit they were reluctant at first to release the massive 20th-anniversary boxed set released today.Shinoda says he wasn’t sure there was enough material to make a big re-release interesting.
