Here in Brazil we have this discussion, a Brazillian band named "Charlie Brown Jr" has a song named "O Côro Vai Comer" (which was released in 1997).. the riff reminds "A Place For My Head" riff... when did the original Xero's "Esaul" was recorded? back in 97 (or before maybe)?
Fun fact, They already opened three Linkin Park Concerts]
1. Chimera Music Festival, 2004 (The first time LP played in Brazil)
2. A unknown Japan concert, Charlie Brown Jr's singer sayed that they opened the show on a interview.
3. Arena Anhembi, 2012 (The band ended in 2013 due the death of two members)
