Steel Mill - LIVE AT THE MATRIX: A limited edition numbered CD box with a 48-page booklet, also known as the first "protection-gap" CD available exclusively as a mail order (not on vinyl topics)

Originally released in 1989 or 1990, this copy is still in pristine condition. If my memory serves me correctly, another box which is covered with reddish brown cloth was also available. Such variant was probably released earlier (and so with a lower limited number) than the grey box. The thick booklet carries many pictures of the band, posters, tickets and memorabilia, which are reproduced in color or black and white.
 

Collecting log: Spirit In The Night - Growin' Up / Rosalita (Come Out Tonight) early U.S. promotion-only custom 7" EP

The white-labeled, promo-only EP originally came in a generic die-cut
company sleeve. Oddly, the sole track from the then latest second
album is placed on SIDE 2 while two songs cut from the previous
debut album are featured on SIDE 1.

For many serious Springsteen fans, June 2 is remembered as the original U.S. release date of the then long-awaited 4th album DARKNESS ON THE EDGE OF TOWN (US Columbia JC 35318). Since this year marks the 40th anniversary of the release year (1978), such fans have already posted a celebration thread in various forums dedicated to the Man and His Music. Serious analog collectors, however, might know that on the same day 44 years ago (June 2, 1974)*, a promotion-only 3-track EP was released to U.S. radio stations, which has become among top collectibles nowadays. While better known for its catalog number prefix "AE7" (which is given to Columbia's promo-only 7" releases), to date, Spirit In The Night - Growin' Up/Rosalita (Come Out Tonight) (US Columbia AE7 1088) is one of the toughest early promo records to find.
