This was Specter's fifth album for Delmark Records.
It saw the Chicago guitarist team up with singer/harpslinger Lynwood Slim (who wrote or co-wrote four of the songs) and organist Jack McDuff.
A smooth and easy listen, Left Turn on Blue shuffles, swings, and bops at the juncture of blues and jazz.
From the blues chestnut "Party Girl" to the Albert Collins instrumental "Tremble" to the steady jazz groove of Slim's "Stop! Hold It," this is a very classy album.
The horns are nicely done, and jazz buffs will particularly enjoy Specter's brief interjections of other tunes into the songs: "Til the End of Time," "Unleavened Soul," and "Killer Jack.".
