Tangerine Dream's final album for Ohr Records, Atem, released in early 1973, was much more accessible than Zeit. The British DJ John Peel was a big fan of Atem and wrote and phoned Edgar Froese to tell him how much he loved their music. Atem became his album of the year 1973, and this might be the reason TD got a contract with the London-based Virgin Records.
In 1987 the album was released on CD for the first time. While the USA release featured the reworked original cover artwork, the UK release had a total different cover design, originating from the boxed set In The Beginning.
Nine years later, in 1996, the CD was re-released again. Though being remastered from the original tapes, this was not a perfect recording like under 1996 studio conditions, but probably the best version of Atem that would ever become available. The cover artwork was very similar to the original LP cover. The CD booklet features sleeve notes taken from the book "Krautrocksampler" by Julian Cope.
In 2001 are pirate CD release was issued in Russia, featuring totally different cover artwork.
In 2004 the album was re-released in Japan with a cardboard sleeve featuring the exact replica of the original LP sleeve.
A very special edition of Atem was released in August/September 2011 by the British Esoteric Records as part of a re-issue of the TD back catalogue of the Pink and Blue Years. The album was released as a double CD, the first disc featuring the original album, while the second one, titled "The Deutschlandhalle Concert", is a re-release of the fan release Tangerine Tree Volume 23: Berlin 1973, featuring a 1973 concert in West Berlin. Like all other re-releases of the Esoteric series, the discs come nicely packaged with a highly informative 16-page booklet, featuring the original artwork, credits, numerous photos and an essay by journalist Malcolm Dome.
In April 2012 the Japanese company Belle Antique re-released the remastered Esoteric version of Atem as double SHM-CD (Super High Material CD), including the bonus disc.
