Brooke Sierra - Voices [Review] November 09, 2019 by Travis Erwin in Music, Electro Pop, Commercial Rating: 4 out of 5 “Brooke Sierra is a talented vocalist and that element shines brightest on ‘Voices,’ though the songwriting is also very strong as well. A nice, smooth commercial groove goes along with the Electro Pop vibe musically, creating a mainstream single as vibrant as any out there.” — Travis Erwin (LA on Lock Blogger)
