My dad had this album on a cassette and I loved to listen to it. Foreigners always had a lot of drive in their music and I can't compare 4 to their other works (except for some Best Of) but as we know - this was very important album for them. And they made it very well. Tension on Juke Box Hero, slow Waiting for a Girl... or Urgent with that sax, you can hardly add anything to it. Actually you can, Break It Up, Woman In Black, I'm Gonna Win... those are hardly just some throw-ins. Of course there is something lighter too (Luanne), but then - why should the album be all that serious, right? And talking about adding - on this CD you can find two songs in their "nearly unplugged" versions - nice bonus, I like both of them.
These are Foreingers in their best - singing is freaking crazy high, music is as hard as needed, but also popy, rocky and everything in nice balance. And for the price, it's no brainer.
