Subtle as a Flying Mallet
Subtle as a Flying Mallet was the second solo album by Dave Edmunds, principally focused on sound-alike remakes of late 1950s and early 1960s hits.
 All of the vocals (except on the live tracks) are by Edmunds, and many of the songs are true solo efforts in that Edmunds also plays all the instruments.
 The album produced two Top 10 singles in the UK, remakes of the Phil Spector hit "Baby, I Love You" and The Chordettes' "Born to Be with You".
 A 2006 reissue of the album includes two former B-sides as bonus tracks. Night Owl (Gerry Rafferty song)
"Night Owl" is a song by Gerry Rafferty.
 It is the second track on his 1979 album of the same name.
 It features a Lyricon solo played by "Baker Street" saxophonist Raphael Ravenscroft.
 The song made the top five in the UK Singles Chart, and along with "Baker Street" is one of two solo efforts by Gerry Rafferty to accomplish this feat. Luke (album)
Luke is the third solo album by Steve Lukather released in 1997.
 It was a much different and more introspective album than Lukather's previous two solo efforts.
 The album is a concentrated collection of many of Lukather's musical influences, and he deliberately let those influences come out on the album.
 "Luke" is an experimental album, and like "Candyman" it was recorded mostly in live sessions with minimal overdubbing and processing afterward.
 "Luke" also features instrumentation not heard on previous Lukather albums such as pedal steel, harmonicas, Mellotrons, and experimental guitar, bass, and drum sounds. Ira (Polish band)
IRA - Polish rock band formed in 1987 in Radom by Jakub Płucisz (guitar), Wojciech Owczarek (drums), Artur Gadowski (vocal, guitar), Dariusz Grudzień (bass) and Grzegorz Wawrzeńczuk (keyboards).
 They gained a wide popularity in Poland in the early nineties, mainly after releasing the "Mój Dom" album, with the hit title song, which was still during their garage and semi-professional days.
 They also gained some local popularity amongst the Polish-speaking citizens in the United States, where they lived and worked for few months.
 After signing a professional contract back in Poland, they released a few albums which didn't prove to be commercially successful (except for the "Mój Dom" follow-up, which was "IRA 1993"), and the band disbanded afterwards.
 Artur Gadowski started a solo career.
 He opened for Brian May before his show in Warsaw in September 1998.
 Artur's solo efforts weren't very successful either, and what success he did gain was largely based on the then legendary status of IRA. In Rock We Trust
In Rock We Trust is the sixth studio album by American hard rock/heavy metal band Y&T, released in 1984 through A&M Records.
 The album became the band's highest charting album at the time, reaching No. 46 on the "Billboard" 200 charts and coming close to gold status; approximately 450,000 copies sold according to Y&T frontman Dave Meniketti. Raw (Crack the Sky album)
Raw, the seventh "proper" album (not counting compilations or live albums) from Crack the Sky, really is more of a John Palumbo solo album under the Crack the Sky banner.
 Other than Jamie LaRitz playing lead guitar, all of the musical parts were played by Palumbo.
 However, "Raw" is more "Rock" than Palumbo's solo efforts.
 The next Crack the Sky album, 1989's "From the Greenhouse", saw the return of a number of veteran CTS members, most importantly guitarist Rick Witkowski. Paul Shortino
Paul Shortino (born May 14, 1953) is an American rock singer and musician who has sung for several bands, including Rough Cutt/The Cutt, Quiet Riot, Bad Boyz, and Shortino.
