Trent Lane is the older brother of Jane Lane and an aspiring musician in the band Mystik Spiral. He is incredibly laid back and spends most of his time asleep. He never wears a watch since he's always late, so watches depress him. He takes weird things in stride, like being in a band with physical Holidays or strangers in his house. He is also the most stable of the band members, and puts up with their arguments and bickering. He usually hangs out with his fellow band-mate, Jessie.Despite his lethargic tendencies, Trent can be somewhat insightful. He helps Daria figure out her relationship with Tom Sloane (after she had gotten over her own crush on Trent). He is very close to Jane, and tried to convince her not to go to college because he would be lonely in the Lane house by himself.
He also has an on-again-off-again relationship with Monique, lead singer of a local band called The Harpies. In "Lane Miserables," he admits that he is scarred by the fact that his mother, Amanda, didn't go look for him when he decided to live in a tent in the backyard.
During his non-waking hours he likes to practice. He's been known to practice the opening to "Come As You Are" for hours, and when rehearsing his own songs the volume is cranked to maximum. He can also get distracted by random things, such as the novelty settings and tunes on a keyboard or comparing vinyl to CD (without realising he's listening to the radio instead). He even sleeps with his guitar, which he and Jane joke is counted as practice.
He also spends his time trying to invent lyrics. He can be inspired to start talking in lyrics or writing them, at any time or place. This too is another bad habit he has while driving, and in conversation (he once started doing a song about betrayal right after he'd tried to reassure Daria that she hadn't betrayed Jane).
While he can play the guitar well enough and nobody has ever commented negatively on his ability to play, his lyrics are usually quite inane. Songs have included lines like "you're cutting off my nose to spite my face/OW! My nose!/OW! My face!". Every song is designed to have simplistic rhymes. Jane has made snarky comments about Mystik Spiral's abilities and chances, and even Trent himself ("Jane's Addition") once said that the songs in the band's second set were "just the ones that weren't good enough for the first set" and that he'd leave if he wasn't in the band.
Despite this, Mystic Spiral keeps getting gigs at The Zon and other places, and grunge fans seem to like it. (This is likely a piss-take on the grunge scene at the time)
Trent is usually enthusiastic (as much as Trent can be enthusiastic) about his music and the band, and will make grand statements about their future and their artistic merit. "Road Worrier" and "See Jane Run" showed flashes of doubt and angst, however: in the former, he worried he might fail, and in the latter he expressed discontent about the state of his career, referring to club audiences as using "[his] the backdrop to their pathetic mating dance... they just want something loud going on so they don't have to talk".
According to "Art Burn", Mystik Spiral never play cover songs as that would undermine their creativity.
