Matchbox Twenty’s Rob Thomas has announced the release of his second solo album, Cradlesong, the follow-up to his 2005 platinum-selling record, ...Something To Be. Thomas’ new single, "Her Diamonds," will debut at radio in mid-April. "I like musical hybrids," says Thomas about the musical direction of the new album. "Like, 'What would it sound like if we took Prince's drummer and mixed him with really amazing Nashville players?' I like to take everyone just left of their comfort zone and record it." Cradlesong is due out June 30.

On Wednesday night in Seattle, three former members of Soundgarden - minus Chris Cornell - reunited for a three-song set at the Seattle stop of Tom Morello's Justice Tour. It was the first time guitarist Kim Thayil, drummer Matt Cameron and bassist Ben Shepherd played together since the band broke up in 1997. Local scene veteran Tad Doyle filled in on vocals as the band tore through "Nothing To Say," "Spoonman" and "Hunted Down." After the show, when asked what he thought of the set, Thayil told Seattle Weekly, "Not bad for an hour and a half of practice after not playing together for 12 years. It was a lot of fun. We played yesterday for a bit but we know all that stuff by heart so we didn't need to practice much."
