According to Clem Burke, the band's drummer, Destri had planned to contribute to the writing and recording of the album, but was ultimately not a part of it.

Panic contains one song in French ("Le Bleu") and two in Spanish ("Wipe Off My Sweat" and "Mirame", though the latter appears only on Collectors Pack version of the album) and features many rhythms and musical styles.

[13] Many of these tracks were released before and after the album: "We Three Kings" (2010), "Don't Stop" (Michael Jackson's "Don't Stop Til You Get Enough", released only as a video[14]), "Horizontal Twist", "Mirame" (Grupo Pesadilla cover), "Please Please Me" (The Beatles cover), "End of the World", "Sleeping Giant" (bonuses to different releases, 2011), "Restless" (published on a Deborah Harry forum with special permissions, 2012[15]), "Dead Air", "Rock On" (David Essex's cover), "Bride of Infinity",[16] "Practice Makes Perfect"[17] (free tracks, 2012).

In an interview with the British newspaper The Daily Telegraph on March 24, 2011, Debbie Harry revealed that the band would be releasing the album themselves (i.e., without a record company) in the United Kingdom as part of a special "Collector's Pack" in conjunction with Future Publishing.

It was made available in the UK from 1 June 2011 in over 3000 nontraditional music retail outlets including Tesco, Asda, Waitrose, WHSmith, and Sainsbury's.
