Bruno Major is surely on the verge of mass popularity. And if he isn’t, he should be. The North London singer/songwriter has released four effortless singles in recent months, and he hasn’t slipped up yet. They are all woozy, jazzy compositions that showcase Major’s smooth voice floating over sparse, quietly shimmering instrumentation. His newest song, “Easily,” is especially romantic, blending classic songwriting with Major’s ever-present jazz influences. It’s some of the best alt-R&B out there, with just the right amount of experimentation to make it intriguing.
