Between Two Worlds is the only album by Norwegian black metal supergroup I.

The album displays a clear influence from classic metal bands, which although present in Abbath's primary band Immortal, is here the sole focus of the music.

A limited edition digipack was released, which includes three bonus tracks.

A limited edition metal box was also released, also featuring the three bonus tracks, and was limited to 1000 copies.

All lyrics are written by Demonaz; all music is composed by Abbath
