This is our first roundup of R&B albums for 2012, even though we've already completed one-third of the year. As we've seen in the past, the world of soul music moves at its own glacial pace, with a release slate much smaller than that of other genres like hip-hop. Soul artists may speak (or sing, rather) less often than others, but when they do, the impact is impressive. New work from Melanie Fiona and Monica debuted in the Top 10 of the album charts, while jazz pianist Robert Glasper's all-star neo-soul "experiment" Black Radio is one of this year's surprise success stories. So here's a rundown of R&B albums issued during the past four months.
