During the great John Lennon revival of the late '80s, Yoko Ono licensed to have the Westwood One Radio Network air scores of unreleased home recordings and demos as the Lost Lennon Tapes radio show. At the time, there was endless speculation about when highlights would be released, likely as a box set…

A two-disc anthology of Rod Stewart's early Mercury recordings, which, in conjunction with the albums he recorded with the Faces, are inarguably his finest (nothing from the Faces records is included). Most of the highlights of his terrific first four albums are here – "Maggie May," "You Wear It Well," "Handbags and Gladrags," "Gasoline Alley" – as well as selections from the lukewarm Smiler, a live album recorded with the Faces, and a couple of rare B-sides.

While it's not a repudiation of her blockbuster, Supposed Former Infatuation Junkie is a clear step forward, teeming with ambition and filled with new musical ideas and different sonic textures. Alanis Morissette's voice still sears, but she has more control over her singing, rarely reaching the piercing heights that occasionally made Jagged Little Pill jarring…

Today, five previously unreleased demos and outtakes from the album are available as part of a digital EP called Blue 50 (Demos & Outtakes). These songs will also be included on Joni Mitchell Archives Vol. 2: The Reprise Years (1968-1971), a compilation coming out in October that will document the period leading up to Blue. Blue 50 (Demos & Outtakes) includes early demos of “A Case Of You” and “California,” an alternate version of “River” that features French horns, an early take of “Urge For Going,” a song that was intended for Blue but didn’t see a proper release until a 1996 greatest hits compilation, and a studio recording of “Hunter,” which Mitchell played live but never officially put out.

Gems: The Duets Collection may bear a title that suggests it’s a compilation, but this 2011 effort is a brand-new album containing nothing but new collaborations between Michael Bolton and similarly minded travelers of the middle of the road…

Eros Walter Luciano Ramazzotti (born 28 October 1963) is an Italian musician and singer-songwriter. Ramazzotti is popular in Italy and most European countries, and throughout the Spanish-speaking world, as he has released most of his albums in both Italian and Spanish…

Hello were one of the more exciting bands of the mid-'70s glam explosion in the U.K., cutting some effervescent, almost giddy slabs of wax bolstered by thundering drums, heavy guitars, huge hooks, and boyish vocals. Not too many were hits, but a quick run through this collection of singles and their flip sides makes it clear that many more should have been. Starting in 1972 with the boogie glam of "You Move Me" and ending with a solo single from their drummer Jeff Allen from 1982, the collection covers a decade's worth of worthy attempts to scale the charts as tastes and sounds shifted around them.

Faithfull pegged her comeback to a brutal survivalist persona, but by this fourth album of her second career, she had mellowed at least to the extent of constructing flowing song structures with her collaborators, Barry Reynolds and Wally Badarou, that eased the bitterness still found in many of her lyrics…

Based on a network TV special that in turn depicted Elton John's Las Vegas show of the same name, The Red Piano is a concert video. It consists of two DVDs and two CDs. Essentially, the package is padded; the second DVD contains a 53-minute "making of" documentary, and the CDs repeat the audio content of the concert with one additional track ("I Guess That's Why They Call It the Blues")…

Although it wasn't immediately apparent, Supposed Former Infatuation Junkie found Alanis Morissette floundering in her success, albeit ever so slightly. Like most arty collegiate types, she reacted to massive success with an instinct to experiment, and since she had sold so many records, she and producer/collaborator Glen Ballard were given free range to do pretty much whatever they wanted, resulting in a muted, fitfully intriguing album that had the feel of a sophomore slump even if it was her fourth record (but who counts those first two records as part of her discography, anyway?)…

Kevin Matthew Gilbert (November 20, 1966 – May 18, 1996, also known as Matthew Delgado and Kai Gilbert) was an American singer, songwriter, musician, composer, producer and collaborator. Gilbert was best known for his solo progressive rock projects, Toy Matinee and his contributions to Tuesday Night Music Club, the debut album by Sheryl Crow.

Slightly more experienced than the ranks of artists discovered online, Danish singer/songwriter Mads Langer had already released two studio albums through Copenhagen Records before impressing Sony bosses with his MySpace-uploaded acoustic EP, Fact - Fiction. Pop - Or??? Despite his new major-label deal, an impressive array of producers including Martin Terefe (KT Tunstall), Ethan Allen (Tricky), and Sacha Skarbek (Bon Jovi), and a backing vocalist in the shape of Darkness frontman Justin Hawkins, his third effort, Behold, is entirely void of bombastics or studio trickery, sticking closely to the emotive Nordic guitar-based pop sound that helped him to get signed in the first place.
