"..In 1978 RTB Big Band celebrated the 30th anniversary by releasing this double album consisted of recent works recorded from March 73 - February 77. The title wasn't as imaginative as the music itself and it was just called 1948-1978 that was a bit misleading for the contest of the album. It had a small inscription at the back of the cover saying "With Guests" so also it might be known under this name as well. Guests in this case on some of the recordings were Dusko Gojkovic, Alan Skidmore, Gerd Dudek, Bora Rokovic. The well known track "Balkan Express" made the original record sought after and quite expensive but very few had a chance to actually hear the whole album."
