Released in 1986 'Trilogy' was Yngwie Malmsteen's 3rd solo album and like Marching Out featured a more song orientated approach. Mark Boals replaced Jeff Scott Soto on vocals. The Johansson brothers remained though and Yngwie handled all Bass guitar duties as well.
This is probably my favourite Malmsteen album and for me features his best song writing to date. I thought Mark Boals did an excellent job on vocals, very Graham Bonnet-esque imo. Some great guitar work here and the album features the track 'Trilogy Suite', imo still the best instrumental guitar track of all time. A great album with a cool but very ostentatious cover, lol!. Easily a 10/10 from me.
