"Surveillance" is the ninth studio album by Canadian hard rock band Triumph, released July 27, 1987. The album was recorded at Metalworks Studios, Mississauga, Ontario, Canada. This is the last Triumph album to feature Rik Emmett until his return to the band in 2008.

This album was an attempt to return to the band's hard rock roots. The previous album was considered too commercial, and fans were clamoring for a return to a more traditional hard rock sound.

This album delivered. Though not commercially successful, the reviews were excellent, and the release was received well by hard-core fans.

The cassette itself is in excellent condition, as is the inlay card. 

The cassette has been tested and sounds great.

This is a promo copy of the album. I worked in an independent record store in the late 80s and early 90s, and this was sent to the store to assist in the marketing/selling of the music. It has a hole drilled into the front cover (see pic) so that the record store could not send it back to the distributor for a credit.
