Fireworks does exactly what it says on the tin - it's a singles collection up to and including Embrace's third album, If You've Never Been.
Embrace are a great band, who have consistently written really good songs, pleasing on the ear, and which you will no doubt have heard regularly over the last ten years. I would say that for a casual fan, or someone who likes their BritPop big and brash, and with an emphasis on optimism, this is a great CD to buy. If you're a regular Embrace fan, there's very little here for you - and I wouldn't buy it just for 3 is a Magic Number.
Embrace have never really made it - following their first album, their singles have only irregularly hit the top 10, and although they do have a legion of fans who love them utterly, they have never really broken the public consciousness. I'm one of the fans, though, and as such would recommend this album thoroughly to anyone who doesn't know them. You'll get thoughtful and clever lyrics, sung in a heartfelt way. At times the music is too big to be contained on a CD, and at times it is bare and exposed. The songs stand up to both ends of the presentation spectrum, and have guided many people through their bad times.
And you could argue that really, Embrace are worth more than this - their album tracks are usually consistently good, and for the fans, a real 'best of' would probably have been much more enjoyable. The songs are great, but this compilation in itself offers little.
