The Crystalairs are a german vocal quartett that started out in the 80`s. (Their earlier name was "Del Romans", they released many records on the "Crystal Ball" - label, what was the influence for their new band name.) In their youth the 4 guys had all collected many 45's from the USA ranging from doo wop to girl group classics, but all their songs are self-arranged self-written originals or unreleased songs from others.
"Night of wonders" is one beautiful example for their harmonic style and their loving vocals.

This is the record that pretty much kicked off the whole 'bastard pop' genre - where a clever bootlegger would fuse the vocal track of one song with the backing of another. Here we have Public Enemy and Herb Alpert (Bittersweet Samba, from Whipped Cream...).

The reason this record (unlike most of the other mash-ups) works so well is that it sounds like a genuine collaboration - the parps of the Tijuana Brass and Chuck D's rap spits meld perfectly. It's a smart-arse idea that becomes a work of art.
