Natin99

Natin99 is the sixth studio album of the Eraserheads released in 1999. With a more mature and serious tone compared to earlier releases, the album produced the tracks Maselang Bahaghari, Tama Ka, Huwag Kang Matakot, and 68 Dr. Sixto Antonio Ave.

Natin99 has been noted for featuring the other band members aside from Buendia as main vocalist, such as bassist Buddy Zabala in Salamin, Tama Ka and Kahit Ano; and drummer Raimund Marasigan in Sino Sa Atin. Buendia is not heard until the fifth track Maselang Bahaghari.

Background
The title of the album is a wordplay on the year it was recorded and released. According to an interview prior to its release, "the term 'natin' started out as a private joke among the band, from a friend who was having difficulty with his Tagalog, "He'd go: 'Patikim naman ng pagkain natin.' Then "natin" evolved to connote almost everything, becoming a generic term. "Kuhain mo na 'yung 'natin" or "Akin na yung 'natin' diyan."

Natin99 was conceptualized when the band saw that their most recent releases were all English songs. Except for some lines in Peace It Together, the album is the band's only all-Filipino album.

Unlike the band's previous recordings, most of the songs in the album were recorded separately, sequenced together with the help of producer Robin Rivera and sound engineer Angee Razul, creating the "peace-ing together" overall theme of the album. The album also employed programmed drum loops and other synthetic elements more than their previous releases.

Lyrically, one recurring theme within the songs in the album is reminiscing old times and moving on, which would later be interpreted by fans as the band's farewell message to each other. After the release of their next album Carbon Stereoxide, Ely Buendia and Marcus Adoro would soon leave the band and the Eraserheads would officially be renamed Cambio in 2002 with new members.
