Heartbeat has two new Studio One CDs out and both are new versions of classic LPs already reissued on CD by Heartbeat in the past.

One of the earliest DJs, Dennis Alcapone was a huge star in reggae circles in the late '60s and early '70s and his "Forever Version," which features recuts of Larry Marshall's "Nanny Goat," The Heptones' "Baby" and The Cables' "Baby Why" are essential Studio One listening. Alcapone's rocksteady-into-reggae style rapping is still fun and is a bridge from the old radio-era chatters to the 1970s roots DJs like...

The Lone Ranger, whose 1979 LP, "On the Other Side Of Dub" -- like "Forever" -- gets an update with bonus tracks, mixes previously unavailable on CD and expanded booklets. Lone Ranger brings his bumpin' late-'70s dancehall style to classic Studio One rhythms like Horace Andy's "Mr. Bassie," Slim Smith's "I'll Never Let Go" and Cornell Campbell's "My Conversation."

Mysteriously, while there was room for bonus tracks, one of the LP's original tracks, "Everything She Want," has gone missing. Seems almost inexcusable for a reissue and since it was one of the best tracks on the LPs, it's a bit sad.

However, both discs sound amazing and the bonus tracks are more than welcome. The missing track excluded, this is the reissue kind of treatment Coxsone Dodd's Studio One LPs deserve.

In the world of reissues, but outside the world of reggae, there's the amazing, Charles Mingus Sextet with Eric Dolphy "Cornell 1964" on Blue Note. This two-CD set captures a stellar unreleased performance by Mingus' band when revolutionary reed man Eric Dolphy was in the front line.

Recorded March 18, 1964 -- three days before Dolphy took part in Andrew Hill's landmark "Point of Departure" session and two weeks before the well-known New York Town Hall concert -- Mingus and company are in top shape.

Pianist Jaki Byard fuels his own composition "ATFW You," Mingus himself is the star of Ellington's "Sophisticated Lady" and the front line of Dolphy, tenor man Clifford Jordan and trumpeter Johnny Coles have plenty of room to spead out as long-time Mingus drummer Dannie Richmond builds a bedrock base.

The group also rode Strayhorn's "A Train," Fats Waller's "Jitterbug Waltz" and "When Irish Eyes Are Smiling" -- alongside four Mingus originals -- to success.

Much like the live Monk sessions released last year, this set is definitely something for jazz fans to celebrate.
