Mag Earwhig! is a 1997 album release by indie rock band Guided by Voices. Following the dissolution of the "classic lineup," band-leader Robert Pollard hired Cleveland rockers Cobra Verde and formed a new GBV unit. This move was somewhat controversial among GBV fans, especially those who were loyal to the lo-fi lineups stretching back to the mid-1980s. Mag Earwhig! is a step-up in production from the band's trademark lo-fi sound, and while the album includes a few tracks with the classic lineup ("Jane of the Waking Universe" being the last), the so-called "Guided by Verde" grouping is the album's dominant force.
