Query: STP completely revamp their entire sound

Nothing like their 1992 release with Core but equally as good, the distorted riffs are toned down on this album and Weiland sings in a totally different style, a true testiment to his abilities as a vocalist, often agreed by many to be their best album, Purple is an alt-rock classic and one of the most creative records of the 90's, songs like Vasoline and the always amazing Interstate Love Song, which everyone likes, fan of the group or not remain radio staples today, even the lesser known songs easily could have been singles. How the beautiful "Still Remains" never became a single will continue to baffle me
