Alex and Eddie Van Halen in 1985.

Alex Van Halen has shared the last track he wrote with late brother Eddie Van Halen.

Unfinished / Between Us Two is a six-minute, mournful yet epic instrumental that mixes acoustic and electric guitars. The track has a similarly cinematic vibe to another instrumental, Respect The Wind, which the pair composed for the soundtrack of the 1996 movie Twister.
