Ur Musig (1993) Cyrill Schläpfer, Rees Gwerder, Jakob Alder, Jakob Duesel

AAM releases the final volume of an acclaimed project to record Mozart’s complete works for keyboard and orchestra. Fittingly, this final instalment includes three works that in various ways are valedictory: K595 is Mozart’s last completed keyboard concert, while K503 is the last concerto of his Viennese years. Louise Alder joins AAM and Robert Levin in an aria for solo soprano, solo keyboard and orchestra; Ch’io mi scordi di te? is a farewell to one of Mozart’s favourite singers, Nancy Storace.

Retro Active is a collection of outtakes and leftovers spanning Def Leppard's entire career. Kicking off the disc, "Desert Song" and "Fractured Love" are two of its most distinctive tracks, harkening back to the band's early (pre-success) days with their rough power chords. After paying homage to some of their heroes with a set of covers (Sweet's "Action" and Mick Ronson's "Only After Dark"), the band tackles a couple of solid, but hardly groundbreaking ballads – "Two Steps Behind" and "Miss You in a Heartbeat" – before stretching out (with mixed results) on the folky "From the Inside." Taken from the Hysteria sessions, the classy "I Wanna Be Your Hero" is another pleasant surprise, and the band reaches all the way back to the beginning by re-recording their first demo "Ride into the Sun." Overall, this is an interesting release which marks the end of a long chapter in the band's history, following the death of guitarist and guiding force Steve Clark. While casual fans might find it confusing, Leppard fanatics will revel in its diversity and informative liner notes.

Released in 1993, The Security of Illusion signaled a rebirth of sorts for Canadian prog rock popsters Saga, as earlier members Jim Gilmour (keyboards) and Steve Negus (drums) were welcomed back into the fold – for the first time since 1985's Behaviour. And as evidenced by the music, the result of the reunion returned the group straight back to their heady early-'80s period, especially on the downright vicious rockers "Mind Over Matter" and "Stand Up," as well as the percussive-heavy album closer, "Without You." Instead of being influenced by what was going on in the rock world circa this time period (here's a hint…well, whatever, nevermind), Saga stick to their guns on The Security of Illusion, and come up with a release that nearly managed to out-rock their Canadian competitor at the time, Rush.

Although it's not on the same level as the best progressive bands – the drums and keyboards are not really up to the challenge presented by the guitars – this album has been rather unfairly written off by some music critics. Their debut begins with their strongest composition: "Voices," whose multiple movements, chorus lyrics of "a million voices singing," broad washes of mellotron, and alternating guitar tones make it sound like an outtake from Yes's "The Ancient." The instrumental "Theme" has some fine jazz-prog sax soloing over a lush backing, and "Dawn of Evening" has a wonderfully taut bassline march pushed to the front of the mix.
