First, of course Lost (9 p.m., ABC) airs its last episode before a monthlong, strike-imposed break tonight. But you can record that. There are rock shows to attend on this first night of spring—a surprising number of them, actually. Try these five on for size:

•The new album from Brooklyn prog/post-rock trio The Big Sleep (pictured) has been slaying me lately. Read my preview to find out what makes Sleep Forever so good, then turn out to Ravari Room, 2657 N. High St., to see them with Waxfang and Alive Band to Watch Rosehips. 9 p.m. doors, $7 cover.

•I've recently become acquainted with a bunch of promising high schoolers known as Kingsli. They're one of those sprawling indie pop ensembles that's always adding new members, and they count accordion, banjo and bouzouki among their tools of the trade. They'll be at Shisha Lounge, 2369 N. High St. tonight with Brooklyn's Polite Sleeper and Karl Blau, which appears to be the K Records Karl Blau who has played with the Microphones and Laura Viers among others. My sleeper pick for the night starts at 8 p.m.

•Reliably rocking garage punks Grave Blankets return to the stage tonight at Cafe Bourbon Street, 2216 Summit St. They're joined by Omaha's infectious, buzzed-about Box Elders and Philly's psychedelic Make a Rising. This lineup is growing on me even as I type. 10 p.m. show, cheap cover.

•A wave of friendship hits Andyman's Treehouse, 887 Chambers Rd., tonight. Insomniac Booking artists Joe Anderl (Dayton), The Gunshy (Chicago) and our very own Melty Melty will play with all their might. This one starts at 10 p.m. too, and I'd wager a $5 cover.

•Hopewell seems to get the short end of the stick a lot, and by listing their show last, I'm probably screwing them over again. But the Brooklyn band, spun off from Mercury Rev and maintaining that band's Neil Youngish vocals and grandiose pop ambitions, is well worth your time. They'll be at Ruby Tuesday, 1978 Summit St., with The Main Street Gospel and TV Eye, tonight at 10. Cover should be cheap on this one too.

When it rains, it pours, even on a sunny day like this one.
