I don't understand much of the information in the CD booklet as it is written entirely in Spanish. However, Omni were a Mexican band that recorded the songs you can hear on Tras El Puente between 1990 and 1993 before the band dissolved in 1994. I don't know whether it has been released on vinyl before, but now it has been released on CD on the Luna Negra label.

The music is instrumental and ranges from 70's influenced progressive symphonic rock to 80's influenced neo-progressive rock. Omni's music is quite soft and mellow with a few exceptions. Although the sound quality is quite poor, this is a really beautiful release and a nice discovery by the Luna Negra label. Worth a listening!
