You've heard of Sly Stone, Stone Temple Pilots, you may even be stoned as you ramble through these pages, but if you've never heard of Foundation Stone , head to The Library on Sunday, Oct. 12 for a rockin' introduction. Hailing from Virginia, this eclectic trio blends hip hop vocals with reggae and jazz in a way that leaves no musical stone unturned. Emily Brass pulls double-duty on sax and vocals, and is joined by Jacques Trudel on bass and Johnny Gilmore on drums. Their sophomore CD entitled, The World We Live In, is distributed by the Homegrown Music Network and was recorded by David Ivory, the Grammy-winning producer behind The Roots' Things Fall Apart and Erykah Badu's platinum-plus Baduism. Whether you're in Raleigh or Durham, The Library's only a stone's-throw away, so skip on over to Chapel Hill on the second Sunday in October to sift through the grooves Foundation Stone is guaranteed to throw at you. 968-6004.
