Just because Kevin Toney is no longer with the Blackbyrds doesn't mean he's traveling light. "Special K," Toney's new solo album, is fortified with an arsenal of keyboards: pianos, synthesizers, clavinet, melodica -- the whole shooting match. Add to that some familiar names -- guitarist Lee Ritenour, percussionist Bill Summers, bassist Abraham Laboriel -- a horn section that boasts trumpeter Oscar Brashear, three lead singers who divvy up their duties, and -- well, you get the idea. Like the Blackbyrds, "Special K" is an extended- family affair. At their best, the Blackbyrds wed a durable, danceable beat to a melodic insouciance; at their worst, an innocuous and derivative pop soul. For those who want more of the good and the bad, "Special K" offers seconds. On the downside, there's the pro-forma funk of "Red Tape," the lush yet oddly unmoving version of John Coltrane's "Naima" and many longwinded arrangements. The pluses include the buoyantly affirmative "Chasing Rainbows," Alton Green's satiny tenor voice, Brashear's evanescent fluegelhorn and Ritenour's arching solo on the rockish title track. All told, it's hard to understand why Toney feels this album represents "a unique blend of musical styles, exploration and attitudes." If "Special K" hits the spot, it's only because its ingredients are familiar. ON RECORD, ON STAGE THE ALBUM: Special K (Fantasy F9616). THE CONCERT: Toney at the Community Warehouse August 13 and 14; at Blues Alley on the 31st.
