Peel hosted frequent live performances (aka "Peel Sessions") that are now emulated in spirit by Peterson's "BBC Sessions" on his internationally syndicated program WorldWide. And while there will never be another John Peel, it is of some certain comfort that Peterson exhibits a similarly intrepid spirit, roaming across musical genres to assemble his weekly free-form playlist. The forthcoming Gilles Peterson Presents the BBC Sessions (Ether Records/BBC Radio) features diverse program highlights from folks like Beck, the Roots, Matthew Herbert, N.E.R.D., Zero 7, and Detroit-based soul singer Dwele, who joins Peterson for this tour, which features DJing and live music. Gilles Peterson waxes eclectic on Saturday, Oct. 15, at Mezzanine; call 625-8880 or visit www.mezzaninesf.com for more info.
