As trio reunions go, 2007 saw a pair of big ones. Earlier in the year, The Police regrouped. From all indications, Sting didn’t end up with one of Stewart Copeland’s drumsticks in his eye-socket, proving that past hostilities had been cast aside. Now, Genesis has returned to the road to shower listeners in a storm of their hits.

Released to coincide with Genesis’s tour, “Turn It On Again: The Hits—The Tour Edition” (Atlantic/Rhino) consists of 34 tracks spread out over two discs. The focus here is primarily on the post-Peter Gabriel version of Genesis in which drummer Phil Collins moved into the spotlight as lead vocalist. The brunt of the hits are drawn from the band’s period of peak popularity—from 1980’s “Duke” album through 1991’s “We Can’t Dance” disc, and run the gamut from the Genesis style prog-rock of “I Can’t Dance,” “Abacab,” “Keep It Dark,” “Turn It On Again,” “Tonight Tonight Tonight” and “Mama” to the kinds of soft-rock ballads that would come to be know as Collins’ trademark, including “Hold On My Heart,” “In Too Deep,” “Throwing It All Away” and “Man on the Corner.” If there is anything impressive about this compilation, it’s the way it digs deeper and generously into the early to mid-1970s portion of the band’s past instead of forsaking it for hit singles.

If you require more than music for the complete Genesis experience, look into the coffee table book “Genesis: Chapter & Verse” (Thomas Dunne Books/St. Martin’s Griffin, 2007, $29.95) by Tony Banks, Phil Collins, Peter Gabriel, Steve Hackett and Mike Rutherford. The band’s “first creative collaboration” in 20 years, the book tells the story of Genesis over the course of 30 years and 30 albums in words and pictures, lots and lots of pictures.

With nearly half as many songs as 2006’s chronological “Gold,” the collection “Classic Cocker” (Capitol) comes up a little short. One example of where corners were cut is the inclusion of a live recording of “The Letter,” from a 1990 Cocker live disc, as opposed to the original 1970 live version. However, what distinguishes “Classic Cocker” from other anthologies is the accompanying DVD that features music videos for “When The Night Comes,” “Shelter Me” and “You Are So Beautiful,” as well as some concert footage.

Cake probably had more hits (i.e. “The Distance,” “Short Skirt/Long Jacket”) than even they would have ever expected. Whether or not there were enough to earn Cake a greatest hits compilation is something else altogether. Nevertheless, apparently there was a bounty of material in the vaults to warrant a compilation such as “B-Sides and Rarities” (Upbeat). A majority of the disc consists of their cleverly ironic choices in cover material, such as “War Pigs,” “Mahna Mahna,” “Ruby, Don’t Take Your Love to Town,” “Strangers in the Night” and “Never Never Gonna Give You Up,” as well as a few originals, including the aforementioned “Short Skirt/Long Jacket.”

Christian music is becoming as unavoidable as the latest Republican scandal, and, as you might have guessed, that’s not necessarily a good thing. One of the pioneers in Christian crossover music, Amy Grant has had her share of highs (numerous hit singles) and lows (a public and messy divorce). Grant’s pleasant, if inoffensive, voice sold musical Bible thumpers as easily as it did pop songs, as you can hear on the 19-track collection “Greatest Hits” (Sparrow/EMI). In addition to the numerous CCM (Contemporary Christian Music) chart-toppers Grant has had throughout her 30-year (!) career, she also scored some secular hits including her No. 1 single “Baby Baby,” which can be found here among numerous others.

Superceding 1985’s double-disc “Best of” compilation by virtually doubling the size of the content, “The Very Best of The Doors” (Elektra/Rhino/DMC) lives up to its name. The trouble is that as with its predecessor, this comp isn’t chronological, and with a band such as The Doors, chronology would work in its favor, especially with more than 30 tracks. Interested in opening more Doors? Check out the triple-disc set “The Doors Live in Boston 1970” (Bright Midnight/Rhino/DMC).

Rock and Roll Hall of Fame inductee Antoine “Fats” Domino is nothing short of a living legend. At almost 80 years old, his contributions to R&B and rock and roll can still be felt to this day. A New Orleans native, Domino is celebrated in the suitably named “Greatest Hits: Walking to New Orleans” (Capitol/EMI), which celebrates his far-reaching impact as demonstrated on classics such as “Ain’t That a Shame,” “All By Myself,” “I’m In Love Again,” “My Blue Heaven,” “Blue Monday,” “I’m Walkin’” and, of course, “Blueberry Hill,” all from the 11-year period of 1950-1961.
