Contagious (1987) was their debut for 'Geffen' and also featured the debut of new members Stef Burns replacing Alves, and Jimmy Degrasso replacing Haze. The album charted 78 in the US But after their tenth effort, appropriately titled Ten (1990), the act splintered apart with Degrasso getting the most press for his joining of Fiona, White Lion and Suicidal Tendencies.
The band reformed in 1995 under the same lineup of Meniketti, Burns, Kennemore and DeGrasso, to occupy the bargain bins with their 'Music For Nations' releases of Musically Incorrect (1995) and Endangered Species (1997), two albums that failed to chart and whose titles could probably describe their future.
Burns, however, was in three bands: Y&T, Huey Lewis and the News, and Italy's Vasco Rossi; not surprisingly scheduling conflicts forced Burns to drop one of the three bands, so in 2003, he left Y&T. He was replaced by rhythm guitarist/backing vocalist John Nymann, who was a childhood friend of the band, and who previously toured on the In Rock We Trust tour as a background vocalist and Rock the Robot, and he sang backing vocals on Down for the Count.
In 2006, Haze was asked to step down and was replaced by Mike Vanderhule on drums.
Facemelter (2010) would be their first studio effort in many years.
April 2016 would see Lang announce he was taking a hiatus from the band to address his alcohol dependency; he would soon later make this a permanent departure. Aaron Leigh would replace him.
Haze died on September 11, 2016, at the age of 61 after a long battle with chronic obstructive pulmonary disease. Original guitarist Alves would die on March 12, 2017, at the age of 63 from ulcerative colitis and inflammatory bowel disease.
In January 2018, Y&T released their first-ever acoustic EP titled Acoustic Classix Vol. 1.
