The Undeveloped Heart EP is the sole single/EP release from Scottish rock musician Ricky Ross' album New Recording.

It contains a new version of "The Undeveloped Heart", which was originally recorded by Ross' band Deacon Blue and re-recorded by Ross for New Recording.

The addition of a driving bass line and guitar to "The Undeveloped Heart (98 Remix)" completes the move of the song from its original form as an understated piano ballad to a track that sits fully in alternative rock territory.

Deacon Blue would regroup in 1999[1] and release two albums before Ross' next solo album, This Is the Life would be released in 2002.

All songs written by Ricky Ross, except where noted:
