Green Day's first two albums,'1039/Smoothed Out Slappy Hours' and 'Kerplunk!', are to be reissued next month.

Billboard reports that it is the first time the albums have been reissued on Green Day's current label Reprise; they were previously reissued by the band's former label Lookout! in 2004.

Among the bonus features on the '1039/Smoothed Out Slappy Hours' reissue are live songs and a 1991 radio interview with Green Day singer Billie Joe Armstrong; there is no bonus material on 'Kerplunk!'.

Green Day are currently working on the follow-up to their 2004 album 'American Idiot'.
