Elijah Blake, “Shadows and Diamonds” review

Modern R&B tends to strut the line between the ultimate cheesy experience (Ne-Yo) and the drug-addled creep (The Weeknd). Elijah Blake, a songwriter who cut his teeth writing tracks for mega stars like Rihanna (“No Love Allowed”) and Rick Ross (“Presidential”) lives in this position of purgatory on his debut, “Shadows and Diamonds.” He follows the typical formula of heartbreak, piano-laden melodies and concepts about being cheated on and doing crazy things to his lover in return.
