Chicago 13: Chicago 13 is the eleventh studio album by the American band Chicago, released in 1979.  The follow-up to "Hot Streets", "Chicago 13" is often critically disfavored.  This would be the band's final release that features lead guitarist Donnie Dacus, who had followed late, founding lead guitarist, Terry Kath.  All band members would contribute to the songwriting (one of only two albums where this is the case, with the other being "Chicago VII").

Chicago 16: Chicago 16 is the thirteenth studio album by the American band Chicago, released on June 7, 1982.  It is considered their "comeback" album because it was their first album to go platinum since 1978's "Hot Streets," it made it into the top ten of the "Billboard" 200, and it produced their second number one single in the United States, "Hard to Say I'm Sorry."  The album was certified gold by the Recording Industry Association of America (RIAA) in August, 1982, two months after its release, and platinum in December, 1982, six months after its release.  The song, "Hard to Say I'm Sorry" was nominated for a Grammy Award for Best Pop Performance by a Duo or Group with Vocal.

Island Records added the video advertisement for the collection to their YouTube account on 18 August 2010.

Adam Leonard (singer-songwriter): Adam Leonard is an English singer-songwriter working mainly in the folk, psychedelic and electronic music fields.  His style is often described as lo-fi and the subject matter of his songs somewhat unconventional.  Since his debut album 'How Music Sounds' in 2003, he has released many EPs, albums and mini-albums on various small labels.  Live performances, which have so far been limited to the UK (Manchester, London and Northern Ireland) are as intriguing as they are rare.  In 2008 he opened for British folk legend Steve Ashley.  He regularly collaborates with other musicians, most notably Pat Gubler (P.G. Six), Ashley Cooke (Pulco), Gareth Davies, and Steven Collins of The Owl Service, a band for which Leonard provided vocals for their 2010 album 'The View From A Hill'.  At the close of 2010, a limited edition album entitled 'Nature Recordings' was released on vinyl only by the London label The Great Pop Supplement.  In 2011 Leonard provided the soundtrack to Claudia Heindel's award-winning independent film Lucky Seven.  In 2012, Nature Recordings was issued on CD by Manchester-based label The Northwestern Series.

Hot Streets: Hot Streets is the tenth studio album (twelfth overall) by the American band Chicago, released in 1978.  In many ways, "Hot Streets" marked the beginning of a new era for the band, turning to disco music, a move which would be derided in retrospect.  It was also the band's first album with all-new material released since their second that didn't have a numbered title.  It was also the first album not to feature original guitarist/vocalist Terry Kath, who died from an accidental self-inflicted gunshot wound in January 1978.  He was replaced by Donnie Dacus on this album.

Morbo (band): Morbo was a Mexican electronica/synthpop/ambient/alternative rock group formed by Juan Carlos Lozano.  Lozano was one of the four founding members of Moenia, which originally included Juan Carlos Lozano as lead vocalist on 1997's debut album 'Moenia' and its 1998 companion remix album 'Moenia Mixes'.  Despite the acclaimed success of 1997's Moenia and 1998's remix album, in itself a risky and previously-unheard of novelty in the Mexican music industry, and due to disagreements between Lozano, Jorge Soto and Alejandro 'Midi' Ortega as to the creative route Moenia should take, Lozano decided to leave Moenia as vocalist with original founding member Alfonso Pichardo returning as lead singer.  Lozano then formed the perhaps less commercial, still synth-oriented, but more guitar-centered Morbo, whose musical vision first came to fruition in 2001's eponymous "Morbo".

Eat Your Face: Eat Your Face is the eighth album by the Huntington Beach, California punk rock band Guttermouth, released in 2004 by Epitaph Records and Volcom Entertainment.  It was hailed as a "return to form" after the stylistic experimentations of 2002's "Gusto", going back to the band's tried-and-true style of fast, abrasive punk rock with tongue-in-cheek humor and sarcastic lyrics.  The album marked a period of transition for the band, whose founding guitarist Eric Davis had left the group early in 2004 and been replaced by Donald Horne.  It was also their only album with bassist Kevin Clark, and their last with longtime drummer Ty Smith.  Lyrically it retained the band’s sense of biting sarcasm and expressed dissatisfaction with the U.S. electoral system and the current state of punk rock in the mainstream, amongst other topics.
