In 1995, Tobias joined the touring band for Alanis Morissette, and from 1999 to 2005 he was a member of the musical duo Splendid alongside his then-wife Angie Hart.

Anthony Kiedis of the Red Hot Chili Peppers spotted Tobias and Mother Tongue in a local nightclub, while they were looking for guitar player to replace John Frusciante.

The album's release was largely received only in Australia; and the band's American exposure was mostly due only to their association with Joss Whedon, creator of Buffy the Vampire Slayer, including on-camera appearances when Splendid performed at The Bronze, the fictional nightclub featured in the series.

[4] Tobias joined Morrissey's touring band in 2004 after the illness of Alain Whyte and eventually became a permanent member of the group, having appeared on all studio recordings and live gigs since.

In 2020, Tobias worked with Morrissey on his upcoming album Bonfire of Teenagers, which was due to be released in February 2023, but in December 2022, it was announced that Capitol Records had backed out of the deal.
