Shout out to praise a publication I discovered this year at Barnes & Noble's magazine rack. waxpoetics™ is a magazine that certainly will appeal to those with eclectic musical tastes. I had the mistaken impression it was a hip hop magazine but actually reading the issue, there is a focus on beats, dee-jays, but also plenty on soul, funk, jazz and even blues. The most recent issue (No. 29) has Herbie Hancock on the cover and a feature on his Mwandishi Band along with stories on soul-blues singer Lee Fields; saxophonist-composer Sam Rivers, composer and pianist Lalo Schifrin, rapper Spoonie Gee along with rediscovery of rare vinyl 45s and albums. Prior issues I have purchased have had feature-interviews on Chuck Brown, Al Green and a similar mix of material that is lively and well-written and a refreshing change of pace from more genre-specific publications.
Wax Poetics has a nice website which includes a digital store as well.
